Subject: PANIC: wrong buffer passed to visibilitymap_clear
Date: Fri, 09 Apr 2021 18:40:27 -0400
Message-ID: <2247102.1618008027@sss.pgh.pa.us> (raw)

Buildfarm members spurfowl[1] and thorntail[2] have each shown $SUBJECT
once in the past two days.  The circumstances are not quite the same;
spurfowl's failure is in autovacuum while thorntail's is in a manual
VACUUM command.  Still, it seems clear that there's a recently-introduced
bug here somewhere.  I don't see any obvious candidate for the culprit,
though.  Any ideas?

			regards, tom lane
