I just ran into this bug which was described in more detail by Daniel Popowich on pgsql-general last November: http://www.postgresql.org/message-id/20626.48966.389612.978...@jupiter.astro.umass.edu
The workaround (running nscd) seems to work fine so far, even if a real fix would be preferrable. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
