It sounds like it's failing to advance that database's datfrozenxid
and/or datminmxid.  You might try to figure out which table is holding
those values back by comparing pg_class.relfrozenxid and relminmxid
to those pg_database columns.  Then look to see if autovacuum is
failing on that table, and/or try a manual vacuum to see what happens.
