Re: [PATCH] Improve REPACK (CONCURRENTLY) error messages for unsupported configurations

While looking these patches over I noticed that we still have some error
reports cases uncovered.  Here's a quick attempt to try and complete
that.

After this patch I see only one uncovered error path, the one that
prevents repacking a temp table of another session.  That would require
an isolation test.  Not sure it's worth the trouble ...  (There's a
bunch of uncovered "elog(ERROR)" cases, but those are mostly just
can't-happen conditions, as I understand).
