An Opus 4.8 review of commit 8185bb5 found two pg_dump+restore failure
scenarios, visible in the attached test patch. (The patch also tests a
REASSIGN OWNED finding, for which I started a distinct thread
postgr.es/m/flat/20260710192533.4f.noahmisch@microsoft.com).
Opus also emitted the attached report about these findings and others. I
didn't examine the others closely. Finding-19, about invalidation callbacks,
stood out as perhaps most exciting if true.
