Re: Change Unix Socket directory at build time

To be fully transparent, the issue I'm dealing with is the following:
If I set a specific unix_socket_directory in postgresql.conf then running
pg_ctl start -w -t5 -D '/val/lib/postgresql/9.4/main'
fails because I believe it cannot verify the server is running because
it's looking for socket in /tmp.
The command fails but the server is started and running.
I don't know if it makes any sense.

On a larger scale I only hope to solve part of the problem because if
I don't configure unix_socket_directory, then pg_ctl will wait for the
creation of a socket in /var/run/postgresql and will believe the
server is not started although it is.

So a more general question would be: "how to make sure pg_ctl expects
the socket in the right place whatever the config is?"
