pg_export_snapshot doc
Hackorum builds and tests every patch posted to the lists, not only commitfest submissions. This is Hackorum's own CI rather than the PostgreSQL project's, and it is still under testing - please report anything that looks wrong.
You can run a PostgreSQL built from this patch straight from Docker, with no checkout and no build:
docker run --rm -p 5432:5432 ghcr.io/hackorum-dev/postgres-patch:t36449psql -h localhost -U postgresBuilt from patchset v1 (message #1), July 28, 2026 at 07:14 AM.
Every patchset is also pushed to a branch of our PostgreSQL fork, so you can check out the same tree CI built. Without a PostgreSQL checkout:
git clone --branch t36449_1 https://github.com/hackorum-dev/postgres.gitIn a checkout you already have, add the fork once:
git remote add hackorum https://github.com/hackorum-dev/postgres.gitthen, for this patchset and every later one:
git fetch hackorum t36449_1 && git checkout t36449_1Patchset v1 (message #1) is on t36449_1
pg_export_snapshot() cannot be used during recovery (i.e. on standby
servers), but it's not documented. IMO this is a bug and should be
fixed. Patch attached.
