OK, I restored the pgsql/data to another server and started up postgres
and this is what I got:
SELECT datname, age(datfrozenxid) FROM pg_database;
datname | age
--------------+-------------
mail_lxtreme | -2074187459
bp_live | 1079895636
template1 | 1076578064
template0 | -2074187459
(4 rows)
mail_lxtreme is a test mail db and I don't care about it. So it could
have been deleted without any worries...
Which databases are a problem? Is it template0 or bp_live and template1?
Thanks
John
