single_copy not needed in GatherPath
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:t50741psql -h localhost -U postgresBuilt from patchset v1 (message #1), July 27, 2026 at 10:47 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 t50741_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 t50741_1 && git checkout t50741_1Patchset v1 (message #1) is on t50741_1
I was curious when create_gather_path() sets single_copy, but could not find
any place in the tree where a path with num_workers==0 is added to
partial_pathlist. This patch removes the field.
