Could you please tell me what I should be doing in this case. Can I drop the replication slot since it is no more used and delete old wal files or will PG be able to recycle them by itself. Yes, just drop the replication slot and the excess files will be removed. Regards Ian Barwick -- Ian Barwick http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
