I'm still concerned about how the critical situation is handled. Your patch just prints a warning to the log and then goes on -- doing what? The warning rolls off the log, and then you have no idea what happened, or how to recover.
I would like a flag in pg_replication_slots, and possibly also a numerical column that indicates how far away from the critical point each slot is. That would be great for a monitoring system. -- 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
