Thread: pgsql: BRIN: be more strict about required support procs
BRIN: be more strict about required support procs With improperly defined operator classes, it's possible to get a Postgres crash because we'd try to invoke a procedure that doesn't exist. This is because the code is being a bit too trusting that the opclass is correctly defined. Add some ereport(ERROR)s for cases where mandatory support procedures are not defined, transforming the crashes into errors. The particular case that was reported is an incomplete opclass in PostGIS. Backpatch all the way down to 13.
