That resulted in this error message:
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
There was no files in /var/run/postgresql/. So that explained why it could not connect to that Unix domain socket.
So where was the socket? Reading this answer I found that I could run this command to figure out where the socket was:
~> netstat -nlp | grep 5432
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 12827/postgres
tcp 0 0 :::5432 :::* LISTEN 12827/postgres
unix 2 [ ACC ] STREAM LISTENING 10994605 12827/postgres /tmp/.s.PGSQL.543
That indicated that the socket was located at
/var/run/postgresql/I was then able to find an explanation here
With that in mind i tried to connect with
~> psql -h /tmp/
psql (9.3.5, server 9.2.7)
Type "help" for help.
That worked and as you can see the server and the client versions does not match. That could explain why the client was compiled with a different default host. Next thing could be to try to update the server from 9.2 to 9.3.
