AFAIR %r is supposed to mean "the earliest segment that can safely be removed"(*). If there's a lot of backlog then perhaps the recovery process has stopped replaying WAL segments for some reason. Is there anything unusual in the slave logs? (*) I *think* the technical definition is "segment previous to the one on which the last restartpoint was set", or something similar. -- Alvaro Herrera http://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
