Hi, We have two postmasters on the same host. They are configured to listen on port 5432 of two distinct IP addresses as follows:
/var/lib/pgsql1/data/postgresql.conf: listen_addresses = '10.0.0.1' port = 5432 /var/lib/pgsql2/data/postgresql.conf listen_addresses = '10.0.0.2' port = 5432
However, if we start the second instance while the first one is running, we get the following error: FATAL: could not open lock file "/tmp/.s.PGSQL.5432.lock": Permission denied
So, lock filename cares only about port number and nothing else. In order to avoid this conflict, how can we configure the name of lockfiles or directory where they are placed?
