Just for clarification, if you set a max_slave_delay it means it is the maximum amount of time WAL replay can be delayed on the slave, _and_ it is the maximum amount of time a query/snapshot can be guaranteed to run without the possibility of being canceled. My point is that these two concepts are linked to the same setting. -- Bruce Momjian <[EMAIL PROTECTED]> http://momjian.us EnterpriseDB http://enterprisedb.com + If your life is a hard drive, Christ can be your backup. + -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
