I'm not sure if there is one. However, usually you su to the postgres
user which will let you in without a password. There you use
"createuser" to make a user for yourself.

Note, it really depends how the distributor has set the system up.
Allowing the "postgres" user password-less access is common because it
allows cronjobs as user "postgres" (backups for example) to run without
any extra configuration.

Have a nice day,

The postgres-User isn't a login-user. Become root (su ), and then
'su - postgres'.

(Debian, but i'm sure with FC5 the same)

Thanks for your immediate reply.

I created new role "db1" and database "db1".

but I cannot login using
psql -Udb1 -ddb1 -hlocalhost
results
Fatal Error : Ident authentication failed for user "db1".

Waiting for your valuable suggestion.
Thanks in advance.

You arn't the user called 'db1'?

Either 'su - db1' and then psql, or change the settings in your
pg_hba.conf for this database and localhost to 'trust'.

Right. As pointed out, the default authentication method "ident" means
that the database user and the system user are linked, so system user
"db1" can login as database user "db1" without a password.

"trust" means anyone can login an anyone, which may or may not be what
you want.

You can define ident maps, where you state that system user "x" can
login without password as database user "y". Check the documentation.

Thanks for all of your valuable replies.

Please tell me, what should i do to login with syntax

psql -Uusername -h192.168.2.2 -dusername(database name).

Because I should be able to login from any login and also from any system.

Set up your pg_hba.conf file to what you need.

I have a small article about this on my site:

http://www.designmagick.com/article/4/

The postgres documentation is here:

In your data directory you will find a file called pg_hba.conf - the
entries in there determine who can log in from what machine with what
sort of authentication.

There are plenty of notes explaining it in the file itself or you can
find explanations in the docs -
http://www.postgresql.org/docs/8.1/static/client-authentication.html

you will probably want to add something like -

# TYPE DATABASE USER CIDR-ADDRESS METHOD
host all all 192.168.2.0/24 md5

and maybe -
host all all 127.0.0.1/32 md5

Hi all,

Now I changed postgresql database administrator login password and then
modified pg_hba.conf file with authentication mathod to md5 for all (roles +
database).

Now can use the folowing syntax from any login.

psql -Uusername -h192.168.2.2 -dusername(database name).

Hence I solved my problem.

Thanks for u all and your replies.
