On Linux:

1. $ [/sbin/]service postgresql initdb

2. $ [/sbin/]service postgresql start

3. The “initdb” procedure will create user “postgres”.

4. Change /var/lib/pgsql/data/pg_hba.conf

from this:

# "local" is for Unix domain socket connections only
local   all         all                               ident sameuser
# IPv4 local connections:
host    all         all         127.0.0.1/32          ident sameuser
# IPv6 local connections:
host    all         all         ::1/128               ident sameuser

to this:

# "local" is for Unix domain socket connections only
#local   all         all                               ident sameuser
local   all         all   trust
# IPv4 local connections:
#host    all         all         127.0.0.1/32          ident sameuser
host    all         all         127.0.0.1/32  trust
# IPv6 local connections:
#host    all         all         ::1/128               ident sameuser
host    all         all         ::1/128  trust

5. Restart postgres

$ [/sbin/]service postgresql restart

6. Test access:

psql -U postgres (no password)
