Subject: pgsql: Fix assertions with RI triggers in heap_update and heap_delete.
Date: Tue, 28 Nov 2023 10:38:20 +0000
Message-ID: <E1r7vTv-007eBz-SW@gemulon.postgresql.org> (raw)
Fix assertions with RI triggers in heap_update and heap_delete.
If the tuple being updated is not visible to the crosscheck snapshot,
we return TM_Updated but the assertions would not hold in that case.
Move them to before the cross-check.
Fixes bug #17893. Backpatch to all supported versions.
