replication_slot_catalog_xmin not explicitly initialized when creating procArray
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:t37067psql -h localhost -U postgresBuilt from patchset v1 (message #1), July 28, 2026 at 05:56 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 t37067_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 t37067_1 && git checkout t37067_1Patchset v1 (message #1) is on t37067_1
Hi,
replication_slot_catalog_xmin is not explictly initialized to InvalidTransactionId.
Normally, there isn't an issue with this because a freshly mmap'd memory is zeroed, and the value of InvalidTransactionId is 0.
If the memory was not 0 for whatever reason, VACUUM would not behave as expected.
See attached patch.
Thanks,
Yi Wen
