Re: Scheduled back up

Sincerely i dunno why this happens and after couple of emails received two
days ago I stoped searching why.
In any case I need it to dump for custom users their dbs data from a php
script.
And now it works, but if i gave the same cmd which run through exec the
pg_dump force me to introduce the user_name and password to continue.

I add some of my emails received about this story.

It's a feature ... or at least an intentional change.

If you want to keep your password in a file, see the ~/.pgpass feature.

It's a feature :-)
The logic is that it is insecure to keep passwords in files.
If you are not concerned about the security in this case, you can switch
to ident or trust identification. That won't prompt you for the password.
