I'm sure it's easier to handle that in easier ways. I imagined we would just issue a message saying "must increase max_connections" and then shutdown. It's easy enough to document that if you change the master you must also change the slave - it's not a very common change after all. -- Simon Riggs www.2ndQuadrant.com PostgreSQL Training, Services and Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
