We have been moving away from measuring in segments. For example, checkpoint_segments was replaced by max_wal_size. Also, with the proposed patch that allows changing the segment size more easily, this will become more important. (I wonder if that will require wal_keep_segments to change somehow.) -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
