How about we default max_replication_slots to -1, which means to use the same value as max_wal_senders? I think this would address the needs of 99% of users. If we do like you suggest, there are going to be very many users who forget to adjust these two values together, and very many who will do it but will be puzzled and annoyed by it. Since we're now pushing the use of replication slots even more (your pg_basebackup change, upcoming logical replication), I think this could be a major source of misconfigurations. -- 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
