Hi,
WHen i run pg_dumpall as the super user [postgres in my case] it asks for a password for every database. I don't know my users passwords. Is there a way to make the super user able to backup without passwords ?
If your users always connect through TCP/IP then you can set local connections to not use passwords but I'm pretty sure there is no way to configure this just for the postgres user (I wish you could).
If you need passworded local connections for users then you'll probably want to turn on 'ident' mode just long enough to set the password for the postgres user (or some other 'super user'). Then you may also want to use the PGPASSWORD environment variable or the .pgpass file to avoid typing the password repeatedly.
