For now I just ignore the first exception.
BEGIN
PERFORM * from dblink_get_result('myconn')as x (t text);
EXCEPTION WHEN datatype_mismatch THEN NULL;
END;
PERFORM * from dblink_get_result('myconn')as x (t text);
thanks,

Hmm. 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
