Beta feature

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:t45758
psql -h localhost -U postgres

Built from patchset v1 (message #1), July 27, 2026 at 03:01 PM.

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 t45758_1 https://github.com/hackorum-dev/postgres.git

In a checkout you already have, add the fork once:

git remote add hackorum https://github.com/hackorum-dev/postgres.git

then, for this patchset and every later one:

git fetch hackorum t45758_1 && git checkout t45758_1

Patchset v1 (message #1) is on t45758_1

Identity sequences shouldn't be addressed directly by name in normal
use. Therefore, requiring them to be added directly to publications is
a faulty interface. I think they should be considered included in a
publication automatically when their owning table is. See attached
patch for a sketch. (It doesn't actually work quite yet, but it shows
the idea, I think.)

If we end up keeping the logical replication of sequences feature, I
think something like this should be added, too.
