Did you know: PG19 is on track to contain the most changes to pg_catalog in historyIntroduction

📌 Overview We recently switched to version 7 (v7) uuid primary keys and saw significantly faster inserts for some tables. The databases were running Postgres 18.4 and mostly used v1 with some v4 uuid values for primary keys. Changing the column default involved running a single alter table command, but did require an exclusive lock on the table, blocking everything including selects. To solve that, we used a short lock timeout and lots of retries. The biggest speedup was 23x faster average execution time for a multi-row insert query called 12000 times per minute on a table with billions of rows.

Introduction The purpose of this blog post is to introduce pg_shmemviz, a new tool to visualize PostgreSQL shared memory. It follows the same approach as pg_walviz, bringing physical layout and byte level navigation to PostgreSQL shared memory instead of WAL segments. Views such as pg_shmem_allocations, pg_buffercache and pg_shmem_allocations_numa are useful...

WAIT FOR in PostgreSQL 19 lets a reader block until the replica has replayed a specific LSN. Measured against sticky routing, sleeps, and synchronous commit, on a replica that misses the write 99% of the time.

Agents can finish the task without teaching you anything. Building expertise now has to be deliberate.

When Rosa first released SolidQueue, she did a fantastic talk on the internals of how it works and what trade-offs she made when building it. You should give it a watch. It’s where I first learned how the SolidQueue approach works, and why it performs as well as it does. I wrote the batch implementation for SolidQueue (with feedback from loads of folks!), so as a complement to Rosa’s original talk, here’s a bit about how the internals of batches work.
