After trying not to add any Rust packages to the PostgreSQL RPM repository, I finally bit the bullet and pushed pgrx and postgresql_anonymizer to the RPM repos, along with packaging guidelines:…
No fact extraction, no graphs, no memory manager. One Postgres table and three search tools scored F1 0.665 on LoCoMo.
Errata: the max_connections post told you to size that parameter for “the replication connections.” On 12 and later, don’t. WAL senders have their own seats, sized by this parameter, and have not drawn from max_connections since PostgreSQL…
The SQL standard is written by a committee I sit on, so what people think it ought to contain is a professional interest of mine. The various social media algorithms seem to know this, and they serve me mostly relevant content. This one…
Use PostgreSQL ALTER FUNCTION SET work_mem to stop one function's sorts spilling to disk without a global change. A production fix: 150 GB a day to 0.
In many real production databases, we often see some tables receiving high-frequency updates (millions per day) and autovacuum running repeatedly (hundreds of times per day). Additionally, those tables can sometimes become heavily bloated.…

Percona Toolkit’s pt-online-schema-change (pt-osc) has long been the preferred solution for performing online schema changes with minimal downtime. Its chunk-based copy algorithm is designed to adapt dynamically to the workload, making it…
and zypp.postgresql.org have a new look! Users no longer have to navigate through pages on the website. Instead, the front page has a clear layout and easy-to-follow instructions. Just select your OS, version, architecture, and PostgreSQL…
Restores are broken in managed OLTP, and they have been broken for a long time. They are slow, and they get slower with scale. The databases that need recovery most, the large production ones, are the ones left waiting the longest.

Two years ago I compared pg_repack and pg_squeeze, the two extensions most of us reach for when a table has bloated beyond what autovacuum will ever give back and VACUUM FULL isn't an option. PostgreSQL 19 changes the starting point.…
