hi, Andy, We are using streaming hot standby, no wal shipping. I checked and base and pg_xlog. both are fine. The extra space is used by /pg_multixact/members(about 5G) and /pg_multixact/offsets(about 1.5G) The doc said that pg_multixact contains multitransaction data used for shared row locks. Is there some process that can clean these two folder when the lock is not needed? Thanks. best, Ying -- View this message in context: http://postgresql.1045698.n5.nabble.com/hot-standby-data-folder-bigger-than-primary-tp5800402p5800505.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
