PL/Java brings functions, triggers, and types in Java. 1.5.1, now in beta,
adds support for PostgreSQL 9.6 and 10 (beta), with a small number of
improvements and fixes.
Project site: http://tada.github.io/pljava/
Release notes: http://tada.github.io/pljava/releasenotes.html
One previously-announced security issue is addressed in PL/Java 1.5.1, as
described in the release notes.
This release introduces support for parallel-safety declarations on
functions in PostgreSQL 9.6. Simple cases work as expected, but PL/Java's
code has not been thoroughly audited to be sure its internal behavior
cannot violate constraints on parallel-restricted or parallel-safe
functions. See the release notes and new user-guide page on parallel query.
This could be a fruitful area for beta testing.
In PostgreSQL 10, trigger transition tables are supported for AFTER
triggers, as described in the release notes.
Notable changes have also been made for the benefit of maintainers of
prebuilt PL/Java packages for software distributions. They allow the
build to be tailored appropriately with options on the mvn command line
and no need to patch the source. One of these allows a working default
for pljava.libjvm_location to be built in, when packaging for
a distribution that has a known, conventional location for Java.
An entire section for package maintainers has been added to the build docs.
Please see the release notes for a more complete list of changes.
1.5.1-BETA1 is available from GitHub as a source release, which builds
quickly using Maven:
Release page: https://github.com/tada/pljava/releases/tag/V1_5_1b1

check_pgactivity 2.2 released
The OPMDG has finally released the version 2.2 of check_pgactivity. Most of the changes were already committed since a long time, but this release finally brings official support for PostgreSQL 9.6 in check_pgactivity.
This release brings some new features :
- support for PostgreSQL 9.6
- add service sequences_exhausted to prevent a sequence running out of ids
- add service stat_snapshot_age to detect a stuck stats collector process
- add service pgdata_permission to monitor rights and ownership of PGDATA directory
- add support for "pending restart" parameters in service settings (9.5+)
- add timeline of in the perfdata output in service wal_files
- add warn/critical thresholds to streaming_delta perfdata
- make thresholds optional in service streaming_delta
Some fixes and changes were also done :
- fix backends_status for PostgreSQL 9.6
- improve and rename "ready_archives" to "archiver"
- fix archive_folder to handle compressed archived WAL properly
- fix a race condition to handle concurrent executions correctly
- fix bug in "human" output format
- fix documentation about default db connection
- now use parameter server_version_num to detect PostgreSQL version
What is check_pgactivity
check_pgactivity is a Nagios-compatible checker to monitor every key features of a PostgreSQL cluster :
- number of sessions, longuest queries, locked sessions, etc
- database size, bloated tables and bloated indexes
- WAL files, archiver state, database dumps
- streaming replication, replication slots
- and many more
check_pgactivity supports several output formats :
- Nagios, strict or not
- binary (Perl-compatible)
Why check_pgactivity ?
The OPMDG was initially formed by Dalibo to support the development of our OPM
monitoring suite. The OPMDG is an informal group of people contributing to OPM and
related tools, and is independant from the company in order to encourage other contributors
to submit patches.
We initially thought about using check_postgres for the OPM monitoring suite, but it lacked
some crucial performance datas and the base code was difficult to maintain. We decided to
write our own Nagios checker from scratch, in a more maintainable manner and with a focus on
a rich perfdata set.
Thus, it's now very easy to extend check_pactivity to support new services or simply support
a new PostgreSQL release - PostgreSQL 10 support is already in the work. The output format is
automatically treated by check_pgactivity, a service just has to return a some variables.

The PostgreSQL Global Development Group announces today that the first beta release of PostgreSQL 10 is available for download. This release contains previews of all of the features which will be available in the final release of version 10, although some details will change before then. Users are encouraged to begin testing their applications against this latest release.
Major Features of 10
The new version contains multiple features that will allow users to both scale out and scale up their PostgreSQL infrastructure:
- Logical Replication: built-in option for replicating specific tables or using replication to upgrade
- Native Table Partitioning: range and list partitioning as native database objects
- Additional Query Parallelism: including index scans, bitmap scans, and merge joins
- Quorum Commit for Synchronous Replication: ensure against loss of multiple nodes
We have also made three improvements to PostgreSQL connections, which we are calling on driver authors to support, and users to test:
- SCRAM Authentication, for more secure password-based access
- Multi-host "failover", connecting to the first available in a list of hosts
- target_session_attrs parameter, so a client can request a read/write host
Many other new features and improvements have been added to PostgreSQL 10, some of which may be as important, or more important, to specific users than the above. Certainly all of them require testing. Among them are:
- Crash-safe and replicable Hash Indexes
- Multi-column Correlation Statistics
- New "monitoring" roles for permission grants
- Latch Wait times in pg_stat_activity
- XMLTABLE query expression
- Restrictive Policies for Row Level Security
- Full Text Search support for JSON and JSONB
- Compression support for pg_receivewal
- ICU collation support
- Push Down Aggregates to foreign servers
- Transition Tables in trigger execution
Further, developers have contributed performance improvements in the SUM() function, character encoding conversion, expression evaluation, grouping sets, and joins against unique columns. Analytics queries against large numbers of rows should be up to 40% faster. Please test if these are faster for you and report back.
See the Release Notes for a complete list of new and changed features.
Test for Bugs and Compatibility
We count on you to test the altered version with your workloads and testing tools in order to find bugs and regressions before the release of PostgreSQL 10. As this is a Beta, minor changes to database behaviors, feature details, and APIs are still possible. Your feedback and testing will help determine the final tweaks on the new features, so test soon. The quality of user testing helps determine when we can make a final release.
Additionally, version 10 contains several changes that are incompatible with prior major releases, particularly renaming "xlog" to "wal" and a change in version numbering. We encourage all users test it against their applications, scripts, and platforms as soon as possible. See the Release Notes and the What's New in 10 page for more details.
This is the first beta release of version 10. The PostgreSQL Project will release additional betas as required for testing, followed by one or more release candidates, until the final release in late 2017. For further information please see the Beta Testing page.

The PostgreSQL Global Development Group has released an update to all supported versions of our database system, including 9.6.3, 9.5.7, 9.4.12, 9.3.17, and 9.2.21. This release fixes three security issues. It also patches a number of other bugs reported over the last three months. Users who use the PGREQUIRESSL environment variable to control connections, and users who rely on security isolation between database users when using foreign servers, should update as soon as possible. Other users should plan to update at the next convenient downtime.
Three security vulnerabilities have been closed by this release:
- CVE-2017-7484: selectivity estimators bypass SELECT privilege checks
- CVE-2017-7485: libpq ignores PGREQUIRESSL environment variable
- CVE-2017-7486: pg_user_mappings view discloses foreign server passwords
The fix for CVE-2017-7486 applies to new databases, see the release notes for the procedure to apply the fix to an existing database.
Any user relying on the PGREQUIRESSL environment variable is encouraged to use the sslmode connection string option,
as use of PGREQUIRESSL is deprecated. CVE-2017-7485 does not affect the 9.2 series. For more information on these issues
and how they affect backwards-compatibility, see the Release Notes.
Bug Fixes and Improvements
This update also fixes a number of bugs reported in the last few months. Some of these issues affect only the 9.6 series, but many
affect all supported versions. There are more than 90 fixes in this release, including:
- Fix to ensure consistent behavior for RLS policies
- Fix ALTER TABLE ... VALIDATE CONSTRAINT to not recurse to child tables when the constraint is marked NO INHERIT
- Fix incorrect support for certain box operators in SP-GiST which could yield incorrect results
- Fixes for handling query cancellation
- Skip tablespace privilege checks when ALTER TABLE ... ALTER COLUMN TYPE rebuilds an existing index
- Fix possibly-invalid initial snapshot during logical decoding
- Fix possible corruption of init forks of unlogged indexes
- Several fixes to postmaster, including checks for when running as a Windows service
- Several planner fixes, among others assorted minor fixes in planning of parallel queries
- Avoid possible crashes in walsender and some index-only scans on GiST index
- Fix cancelling of pg_stop_backup() when attempting to stop a non-exclusive backup
- Updates to ecpg to support COMMIT PREPARED and ROLLBACK PREPARED
- Several fixes for pg_dump/pg_restore, among others to handle privileges for procedural languages and when using --clean option
- Several fixes for contrib modules, such as dblink, pg_trgm and postgres_fdw
- Fixes to MSVC builds, such as using correct daylight-savings rules for POSIX-style time zone names and supporting Tcl 8.6
- Several performance improvements
- Fix cursor_to_xml() to produce valid output with tableforest = false
- Fix roundoff problems in float8_timestamptz() and make_interval()
- Fix pgbench to handle the combination of --connect and --rate options correctly
- Fixes to commandline tools such as pg_upgrade and pg_basebackup
- Several fixes to VACUUM and CLUSTER
Users of replication tools based on logical decoding, as well as users of unlogged indexes, should consult the release notes
for potential extra steps during the upgrade.
This update also contains tzdata release 2017b with updates for DST law changes in Chile, Haiti, and Mongolia, plus historical corrections for Ecuador, Kazakhstan, Liberia, and Spain. Switch to numeric abbreviations for numerous time zones in South America, the Pacific and Indian oceans, and some Asian and Middle Eastern countries. The timezone library is synchronized with IANA release tzcode2017b.
EOL Warning for Version 9.2
PostgreSQL version 9.2 will be End-of-Life in September 2017. The project expects to only release one, or two, more updates for that version. We urge users to start planning an upgrade to a later version of PostgreSQL as soon as possible. See our Versioning Policy for more information.
All PostgreSQL update releases are cumulative. As with other minor releases, users are not required to dump and reload their database or use pg_upgrade in order to apply this update release; you may simply shut down PostgreSQL and update its binaries.
After update, users of replication tools based on logical decoding, as well as users of unlogged indexes, should consult the release notes
for potential extra steps during the upgrade. See the Release Notes for more details.
Users who have skipped one or more update releases may need to run additional, post-update steps; please see the release notes for earlier versions for details.

Oxford, United Kingdom - May 4, 2017
2ndQuadrant is pleased to announce the release of pglogical 2.0 – the next generation in logical replication for PostgreSQL. This version will continue to be supported until EOL for PostgreSQL server versions 9.4, 9.5 and 9.6 and will also work with PostgreSQL 10 due to release in Fall 2017.
The pglogical 2.0 release brings new features allowing it to be used for even more use-cases. It also includes several bug fixes and behavior improvements, including:
- Row filter - specify SQL expression which should be used on upstream to filter rows for replicated table
- Column filter - specify list of columns that should be replicated, this allows replication of just some columns from a table
- Windows support - pglogical can be now used with PostgreSQL running on Windows as both provider and subscriber (has to be built from the source at the moment)
- Delayed replication - it’s now possible to set delay for how long behind the downstream should be when replicating data
- Postgres-XL support - Postgres-XL can become a pglogical subscriber, which means you can replicated from PostgreSQL to Postgres-XL directly
- New command line tool pglogical_create_subscriber which can convert physical standby (or base backup) into pglogical subscriber
- Performance improvements for applying transactions containing many INSERTs (including transactions that did large import using COPY)
- Improved behavior of TRUNCATE, especially the TRUNCATE triggers
- Users executing DDL in database no longer need USAGE privilege on pglogical schema
- Fixed reporting of false positives on UPDATE conflicts
- Log level for conflicts can now be changed
pglogical is a logical replication system implemented entirely as a PostgreSQL extension. Fully integrated, it requires no triggers or external programs. This alternative to physical replication is a highly efficient method of replicating data using a publish/subscribe model for selective replication.
2ndQuadrant leads the drive for improving the enterprise functionality for PostgreSQL, continuously contributing major features to every release for performance, replication, business intelligence and usability.
pglogical has been developed by 2ndQuadrant. It is open source and fully supported for 2ndQuadrant 24/7 Support customers. We also offer consulting services to help organizations with application development, conflict handler design, cluster design, deployment, feature development and performance analysis.

Yohz Software has released PgComment, a FREE Windows tool to easily add/modify comments to your database objects.
PgComment reads your database schema in seconds, and displays the schema in a hierarchical tree view, together with any existing comments. You can then edit the comments directly in the tree view.
With PgComment, you can add comments to tables, columns, indexes, views, domains, sequences, and functions.
Changes are cached locally, and sent to the server in a batch when applied, so you do not have to wait for individual COMMENT ON commands to complete after each change. This allows you to work faster.
Used together with DB Doc, our PostgreSQL schema documentation generator, PgComment allows you to delegate the task of documenting the database objects to the users who are most familiar with the database objects.
For more information on PgComment, please visit http://www.yohz.com/pgc_details.htm, or download the installer.

We are very excited to announce the release of AgensGraph v1.1. It includes both new features and many useful improvements. Since we released AgensGraph v1.0, our team has been hard at work researching and building the best AgensGraph solution for database over the past two months. With improved features and upgraded performance, AgensGraph makes it easier for you to manage, analyze and store your data.
Let’s take a look at the new features and improvements:
? MERGE Clause
The MERGE specification is a convenient way to verify specific patterns in a graph. If there is no such pattern, AgensGraph creates the specified pattern automatically. Users can also define the additional behaviors using ON MATCH and ON CREATE optional clauses.
? Variable Length Edge Pattern Queries
AgensGraph v1.1 is twice as fast as the previous version (v1.0). Using variable length edge pattern is a concise way to specify degrees of relationships between entities such as finding friends of a friend. This is one of the reasons why users choose graph database over relational database.
? External modules
In AgensGraph v1.1, two external modules have been added: Hadoop FDW and HyperLogLog datatype.
Hadoop FDW is a foreign data wrapper which connects HIVE systems to access HDFS files in AgensGraph. Using Hadoop FDW, the data residing in Hadoop can be easily imported into AgensGraph.
AgensGraph v1.1 is a minor release but contains major improvements. There will be more features and modules introduced in the coming months. We will update you accordingly. Please visit AgensGraph v1.1 Release for more detailed information.
