We plan to migrate from 8.1.X to 8.2 . I understand that XID wraparound has changed with the 8.2 release (maintained per table versus entire database). XID wraparound is important for us as we have large databases (800Gb +) and also use lot of partitioned inherited tables. Is XID tracking done per inherited table (independent of parent?) ... If a parent table is just a dummy to implement partition..do we need to worry about XID wraparound for this table (assuming no data makes it to this physical table) -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
