postgres: localhost not connecting

My `postgreSQL.conf` looks like ``` # - Connection Settings - listen_addresses = '*' # what IP address(es) to listen on; # comma-separated list of addresses; # defaults to 'localhost', '*' = all # (change requires restart) port = 5432 # (change requires restart) ``` and I also know that postgres is running ``` air:data postgres$ ps -aef | grep postgres 504 16474 16473 0 11:34AM ?? 0:00.00 postgres: logger process 504 16476 16473 0 11:34AM ?? 0:00.00 postgres: writer process 504 16477 16473 0 11:34AM ?? 0:00.00 postgres: wal writer process 504 16478 16473 0 11:34AM ?? 0:00.00 postgres: autovacuum launcher process 504 16479 16473 0 11:34AM ?? 0:00.00 postgres: stats collector process 0 16087 16078 0 10:54AM ttys001 0:00.03 su - postgres 504 16473 1 0 11:34AM ttys001 0:00.22 /Library/PostgreSQL/9.1/bin/postgres -D/Library/PostgreSQL/9.1/data 504 16484 16088 0 11:34AM ttys001 0:00.00 grep postgres ``` But I am not able to connect ``` psql -Uuser -W Password for user user: psql: 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"? ``` Also, when I run the following ``` lsof -i tcp:5432 ✘ me@air11:37:13 ⮀ ~ ⮀ netstat -a | grep postgres tcp6 0 0 *.postgres *.* LISTEN tcp4 0 0 *.postgresql *.* LISTEN ``` It says nothing running on `port 5432` What am I missing? UPDATE My `pg_hba.conf` looks like ``` # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all all md5 # IPv4 local connections: host all all 127.0.0.1/32 md5 # IPv6 local connections: host all all ::1/128 md5 ```
