Thread: Connect to postgres from a script using password

Hi,

Can anyone tell me how to connect to postgres from a
shell script using password. If i use psql -UUser db
-W option it prompts for password everytime..
Is there anyway we can have the password included in
psql login command.?

Thanks
Priya

You can keep the password in ~/.pgpass or you can use ident authentication.
In at least some versions you can pass it through an environment variable,
but you don't want to do that if there are untrusted users with shell
access to the host, as environment variables are typically visible to other
users.

Try environmental variables. I use this one:

==========================
export PGPASSWORD=password
export PGUSER=username
psql dbname
==========================

Using ~/.pgpass might be another alternative.
