Not necessarily. The port number in the PID file is only used for pg_ctl to contact the server, and for that it only needs some port, not the primary one. Also, we write the first listen_address into the PID file for the same reason. So if you think there should be a primary port, then there should also be a primary listen_addresses. > and also affects the naming of any UNIX sockets created. Why would that matter?

I would like something where you set host and port together, so you can listen on port 5432 on localhost, and port 5433 on *, for example. So maybe listen_addresses = localhost:5432,*:5433 Web servers usually allow that sort of thing, but if you dig deep there, the configuration settings and their interactions can get pretty complicated. For example, you can usually set a default port and then override it in the listen_addresses equivalent. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
