postgres: localhost not connecting - postgresql

Question

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

Answer 1

In pg_hba.conf:
host all all 127.0.0.1/32 trust
last column change to trust

Answer 2

You need to use the psql program that comes that the PostgreSQL package that you installed instead of the psql in the /usr/bin directory that is part of the Apple system.
For example, if using postgres.app, they say in their documentation:
Mac OS 10.7 ships with an older version of PostgreSQL, which can be
started with the following command:
$ psql -h localhost PostgreSQL ships with a constellation of useful
binaries, like pg_dump or pg_restore, that you will likely want to
use. Go ahead and add the /bin directory that ships with Postgres.app
to your PATH (preferably in .profile, .bashrc, .zshrc, or the like to
make sure this gets set for every Terminal session):
PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"
Once your
path is correctly set up, you should be able to run psql without a
host. (If not, check that the correct version is being loaded in the
PATH by doing which psql)
If using another source of pre-packaged postgresql, it's the same thing with different paths.

Answer 3

Not sure why this was happening, but I found postgresapp.com which is pretty good to use
I am using this with http://www.pgadmin.org/ and I am running it smoothly so far

Answer 4

you can try to stop service and agian start the service. once you reload the configuration file. check again while it is working or not.
