PostgreSql - Create user and DB

To create a user:
createuser -d -P -l username
To create a database:
createdb -W -U username dbname
Test with:
psql -d dbname -U username -W
if you get an error message saying "psql: FATAL: Ident authentication failed for user 'username'"
vi /etc/postgresql/8.4/main/pg_hba.conf
By default Postgresql uses IDENT-based authentication. All you have to do is allow username and password based authentication for your network or webserver. IDENT will never allow you to login via -U and -W options. Append following to allow login via localhost only:
local all all trust
host all all trust
for any host:
local all all trust
host all all trust
You will have to restart the service
/etc/init.d/postgresql-8.4 restart
NOTE: If you want the server to prompt for a password instead of trust use password but this method sends the password in cleartext over the network.
