Passwordless postgresql login

We can log in postgres without promoting/enter password through psql.

syntax:

sudo -u user_name psql db_name

i.e
sudo -u postgres psql postgres

postgres -- database name, if you omit this by default it will log in with postgres database only

may forget the password simply enter into psql mode simply by above command and alter user with new password by

alter user user_name with password 'new_password'


note:

use sudo for log in if you face any issue by log in throuogh

su postgres
psql
