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.

won't retrysuccessCI history

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:t50853
psql -h localhost -U postgres

Built from patchset v1 (message #1), July 27, 2026 at 10:35 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 t50853_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 t50853_1 && git checkout t50853_1

Patchset v1 (message #1) is on t50853_1

I noticed that WinGetFuncArgInFrame() in nodeWindowAgg.c is hard to
read/understand. I think part of the reason is, it is long and has
large switch case and uses goto. I propose to refactor the function to
mitigate the issue. With attached patch, the large switch case is
moved to a new static function WinGetSlotInFrame().

Best reagards,
