The 2 or 3 minutes every few months to go from 8.1.x to 8.1.x+1, or the half a day of downtime when some horrendous bug takes down the whole site because you didn't update it. Seriously, that unfozen template0 bug that Alvarro mentioned is one of those kinds of bugs. Nothing like your db going down in the middle of the day with an error message that it's going down to prevent txid wraparound induced loss, please run vacuum on all your databases in single user mode. If you can't find set aside a minute or two at 0200 hrs, then don't be surprised when you get one of those failures. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
