As promised in previous commit. Upstream patch: commit bd0a2609 Author: Tom Lane <tgl@sss.pgh.pa.us> Date: Fri Jun 1 19:38:07 2007 +0000 Make CREATE/DROP/RENAME DATABASE wait a little bit to see if other backends will exit before failing because of conflicting DB usage. Per discussion, this seems a good idea to help mask the fact that backend exit takes nonzero time. Remove a couple of thereby-obsoleted sleeps in contrib and PL regression test sequences.
