## Source excerpt

Hot off the press: pgcopydb v0.18 is out! It's the biggest release the project has had -- 88 commits since v0.17, which shipped in August 2024. I took a break from my Open Source responsibilities for a while, because I was lacking employer support to make it happen. What is pgcopydb pgcopydb copies a PostgreSQL database to another PostgreSQL server, as fast as possible when physical file copy isn't available. It parallelises the COPY across all tables simultaneously, builds indexes in parallel after data is loaded, and supports Change Data Capture via logical replication for minimal-downtime migrations. It is designed to be restartable: state is tracked in a local SQLite catalog so an interrupted run can resume where it left off. Headline Features of pgcopydb v0.18 v0.18 brings compatibility with PostgreSQL 16, 17, and 18; a pgoutput-default CDC engine with significant reliability and performance improvements; regular-expression-based filtering; Citus-to-Citus migration support; and 24 bug fixes.
