You will need to modify pg_hba.conf file in the directory which you
initdb'ed and restart the database.

this file is well documented and reading it is a good investment.
There are several options to allow connecting . mentioned
below are roughly in order or security. you need to add/modity
/uncomment the lines near the end of this file.

local all all trust # very trivial

will allow any user to connect from same machine to any database without
any password.

local all all md5

(same a above but will ask password)

host all all 192.168.0.100/32 md5

(same a above but allows connection from said address range)

you can choose any config based on your requirement but make
sure it secure enough eventually.
