05.21.2026 - pg_mentat 1.3.0 released -- Datomic-compatible Datalog inside PostgreSQL

I am pleased to announce the first public release of [pg_mentat] (https://github.com/gburd/pg_mentat), a PostgreSQL extension that implements Datomic's data model -- immutable facts (datoms), schema-first attributes, a full Datalog query compiler, the pull API, time travel, and ACID transactions -- entirely inside PostgreSQL.
