pgsql: Now that we've rearranged relation open to get a lock before - Mailing list pgsql-committers

Log Message:
-----------
Now that we've rearranged relation open to get a lock before touching
the rel, it's easy to get rid of the narrow race-condition window that
used to exist in VACUUM and CLUSTER.  Did some minor code-beautification
work in the same area, too.
