For now I just ignore the first exception.

I can reproduce this in 8.4 too, but it seems OK in 9.0. The only one of the 9.0 commits that seems likely to be relevant is http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=56cbb61 1ec749ba867a4cfc09c8b7df0f4446620 which looks a bit overcomplex for a back-patch. Joe, any thoughts? regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
