Amol-
Answers to your several questions:
> $psql Connection to database 'amol' failed. FATAL 1: Database
> amol does not exist in pg_database
This message simply means the database doesn't exist yet.
> command $createdb mydb Connection to database 'template1' failed.
> FATAL 1: SetUserId: user 'amol' is not in 'pg_shadow'
This looks like the heart of your problem. You need to set your linux user
to postgres ("su - postgres" from root), and do a "createuser amol" if you
want to use the databse from your account.

Generally, by default the authorization method is "peer sameuser" after
initial install, meaning that if you are logged into linux as a user that
exists in pg_shadow, you are authorized. the user "postgres" is initially
there, so just su to postgres while you create other user accounts using
createuser. Later you may want to choose a more secure auth method. Search
the interactive documentation for "pg_hba.conf" to learn more about
authorization methods & how to set them.
Hope this helps you get started! Welcome to postgresql.
