automatic pg_dumpall

Colleagues,

If I have to organize an automatic nightly pg_dumpall, how do I handle
authentication ? I do not want to create a passwordless superuser (or
trust method in pg_hba.conf), and there is noone to enter the password
manually.  Is there another recipe?

Thanks in advance for any input.

I am afraid you did not understand my question. In your scenario,
pg_dump will ask for the authentification of the user "postgres". I
have already stated above that I do not want to create a passwordless
superuser (or trust method in pg_hba.conf).

Who do you trust? If you trust the system account that pg_dump is running
under (and if you don't you have problems) and pg_dump is being run on
the same machine as the postgres server, use a domain socket connection
and ident authentication. This doesn't work on all OS's, but in works on
a number of common ones.
