Backporting citusdata#8235 PG18 and PG latest minors ignore temporary relations in `RelidByRelfilenumber` (`RelidByRelfilenode` in PG15) Relevant PG commit: postgres/postgres@86831952 Here we are keeping temp reloids instead of getting it with RelidByRelfilenumber, for example, in some cases, we can directly get reloid from relations, in other cases we keep it in some structures. Note: there is still an outstanding issue with columnar temp tables in concurrent sessions, that will be fixed in PR citusdata#8252 (cherry picked from commit daa69be)

…1) (#8629) ## Problem The 1ES self-hosted pool (`1es-gha-citusdata-pool`) is no longer dispatching jobs, so the **required** `check-arbitrary-configs` jobs sit `QUEUED` indefinitely. This blocks **every** open release-12.1 PR (#8519, #8328, #8306, #8626, #8627) from merging despite all other required checks passing. ## Fix Flip the `test-arbitrary-configs` job's `runs-on` from the dead self-hosted 1ES pool to `ubuntu-latest` — a one-line backport of the config already shipping on `main`. ## Why it is safe - `main` already runs this exact job/suite/container on `ubuntu-latest`. - Required-check **names** (`PG14 - check-arbitrary-configs-0`, ...) derive from the job `name:`, not `runs-on`, so branch protection is unaffected. - AC was the **only** job still pinned to the self-hosted pool; everything else already runs github-hosted. ## Rollout Merge this first, then "Update branch" on the 5 open PRs so they inherit the fix and their AC checks run on github-hosted runners. Unblocks the release-12.1 serial-merge queue. Co-authored-by: Ibrahim Halatci <ihalatci@microsoft.com> Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
