Run
sudo port install postgresql92
and then
sudo port install postgresql92-server
Once the server has been installed, run the following
To create a database instance, after install do
sudo mkdir -p /opt/local/var/db/postgresql92/defaultdb
sudo chown postgres:postgres /opt/local/var/db/postgresql92/defaultdb
sudo su postgres -c ‘/opt/local/lib/postgresql92/bin/initdb -D /opt/local/var/db/postgresql92/defaultdb’
The output you will see
The files belonging to this database system will be owned by user “postgres”.
This user must also own the server process.
The database cluster will be initialized with locale “en_GB.utf-8”.
The default database encoding has accordingly been set to “UTF8”.

WARNING: enabling “trust” authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
–auth-local and –auth-host, the next time you run initdb.
Success. You can now start the database server using:
/opt/local/lib/postgresql92/bin/postgres -D /opt/local/var/db/postgresql92/defaultdb
or
/opt/local/lib/postgresql92/bin/pg_ctl -D /opt/local/var/db/postgresql92/defaultdb -l logfile start
Switch to the postgres id using
sudo su – postgres
Then run the following command
/opt/local/lib/postgresql92/bin/postgres -D /opt/local/var/db/postgresql92/defaultdb
The output will be
LOG: database system was shut down at 2013-02-28 14:43:36 GMT
LOG: database system is ready to accept connections
LOG: autovacuum launcher started
Once you run the above command as suggested, the server will be available for use
