Mountain Lion Postgres could not connect

Question

After my update to mountain lion my postgres doest work. It is still running but my applications cant connect to it anymore.

$ ps aux | grep postgres
postgres         204   0.0  0.0  2446960    836   ??  Ss    7:31AM   0:00.59 postgres: stats collector process

postgres          64   0.0  0.2  2478600   7972   ??  Ss    7:31AM   0:00.26 /Library/PostgreSQL/9.1/bin/postmaster -D/Library/PostgreSQL/9.1/data
anezio         10205   0.0  0.0  2432768    624 s000  R+    8:01AM   0:00.00 grep postgres

and my applications are returning this error:

could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

I still can connect to psql with the command /Library/PostgreSQL/9.1/bin/psql -U postgres

Seems like something is not pointing to the right place

I've solved this problem by uninstalling and re-installing it
