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:t253708
psql -h localhost -U postgres

Built from patchset v1 (message #1), September 20, 2026 at 11:33 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 t253708_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 t253708_1 && git checkout t253708_1

Patchset v1 (message #1) is on t253708_1

Hi,

Standalone backends always use the BOOTSTRAP_SUPERUSER, it might be
good to report it to PgBackendStatus so that we can query it even in single
user mode.

Thoughts?

Why should we care for a process kicked by postgres --single? No
other processes can look at the information provided. :)

Why should we care for a process kicked by postgres --single?  No

Yeah, I find it by querying pg_stat_activity in single user mode and the result
doesn't show the username, which looks a bit strange though harmless.
