I dont'n know what is wrong with the postgresql.conf

Here is the config file
postgresql.conf

# PostgreSQL's Database Directory
PGDATA=/var/lib/postgresql/data

# Logfile path: (NOTE: This must be uid/gid owned by
the value of $PGUSER!)
PGLOG=/var/lib/postgresql/data/postgresql.log

# Run the PostgreSQL user as:
PGUSER=postgres

# Extra options to run postmaster with.
# If you want to enable TCP/IP for PostgreSQL, add -i
to the following:
PGOPTS="-N 1024 -B 2048 -i"

#tcpip_socket = true
