Yeah, that's fair -- we discussed this kind of behavior during
development and I was unsure about being strict about it, so avoided it.
+1 , thanks for the patch.
This is mostly straightforward to fix, as attached (though the error
message needs work),
I have reviewed the patch except the below things and
LGTM until now.
but I hit a snag with multiple inheritance -- if
you apply this patch, you'll see failures in the pg_dump and pg_upgrade
tests. I don't have any ideas to fix this right now, but I'll keep
thinking about it.
I need to look further into these parts,and will update once
I have something solid.
