Tom Lane 6f1321d5ae Restore the portal-level snapshot for simple expressions, too. ... Commits 84f5c2908 et al missed the need to cover plpgsql's "simple expression" code path. If the first thing we execute after a COMMIT/ROLLBACK is one of those, rather than a full-fledged SPI command, we must explicitly do EnsurePortalSnapshotExists() to make sure we have an outer snapshot. Note that it wouldn't be good enough to just push a snapshot for the duration of the expression execution: what comes back might be toasted, so we'd better have a snapshot protecting it. The test case demonstrating this fact cheats a bit by marking a SQL function immutable even though it fetches from a table. That's nothing that users haven't been seen to do, though. Per report from Jim Nasby. Back-patch to v11, like the previous fix. Discussion: https://postgr.es/m/378885e4-f85f-fc28-6c91-c4d1c080bf26@amazon.com		2021-06-22 17:48:39 -04:00
