BUG #16468: Doc: release note 13, missing GUC enable_groupingsets_hash_disk
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:t70059psql -h localhost -U postgresBuilt from patchset v3 (message #3), August 18, 2026 at 04:21 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 t70059_3 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 t70059_3 && git checkout t70059_3Patchset v3 (message #3) is on t70059_3

Bug reference: 16468
Logged by: TAKATSUKA Haruka
Email address: harukat@sraoss.co.jp
PostgreSQL version: 13beta1
Operating system: Any
Description:
Allow grouping sets to use hash aggregation with disk storage for large
grouping set results (Jeff Davis)Previously, hash aggregation was avoided if it was expected to use
more than work_mem memory. This is controlled by enable_hashagg_disk.
It seems to me that the "enable_hashagg_disk" is mistaken for
"enable_groupingsets_hash_disk".

Good catch. This is not fixed yet on HEAD. Adding Bruce in CC as
that's part of the release notes.
