First of all, my gratitude to Adrian and David for taking the time to reply to my call for help; a 1k thanks to you kids.
Having stated the above, PostgreSQL provides a default database
namely 'postgres'. Taking advantage of this service, I have change
the 'psql' statement to 'psql -d postgres -U my_linux_user_name
-W', I then entered my Linux account login password and got this
error messages :
$ psql -d postgres -U my_linux_user_name -W
Password:
psql: error: connection to server on socket
"/var/run/postgresql/.s.PGSQL.5432" failed: FATAL: Peer
authentication failed for user "my_linux_user_name"
I also, using 'postres' account, have created another user
account, chispa, who is a superuser; when trying to login as
'chispa' and using the above statement (psql -d postgres -U
chispa -W ) PostgreSQL throws the same
error message.
What am I doing wrong?
Is there a webpage that explains how to login to PostgreSQL as
other than 'postgres'?
Thanks in advance.
psql -d mydb -U myuser -W
