RE: Backing up postgresql databases

Is there any reason why programs like this could not be given a simple
properties file which contains the username and password. This file could
then be passed on the command line, but nobody (other than, say, root, or
postgres) would have access to it at all. I've seen a number of systems use
this type of solution, and although it appears superficially useless (am I
opening myself to be shot down or what ;-), the security of the file system
creates (as far as I can see) reasonable safety.

Just my EUR25...
