connect to postgres from shell scripts

Hi,

I would like to know how to connect to postgres from
shell scripts using a password protected user.

Is there a way to embed the password in psql login.
It keeps prompting for the passwords.

Any hint is appreciated.

Thanks
Priya

psql checks for PGUSER, PGPASSWORD, PGHOST, PGPORT, PGDATABASE and some
other environmental variables. Export relevant values to the parameters.

http://www.postgresql.org/docs/8.0/...bpq-envars.html

Also there's a .pgpass file thing:

Take a look at the .pgpass file, some info at:

http://www.postgresql.org/docs/8.0/...bpq-pgpass.html

Doing that, your password is still as secure as your .pgpass file,
which hopefully is more secure than your script.

PGPASSWORD is deprecated because it is insecure on some platforms
(to wit, those where other users can see a process' environment
variables via ps). The ~/.pgpass file is the recommended way to go.

psql is the simple way.

Use the .pgpass file to store the password.
