A program that acts as an interface between the rdbms and whatever wants the 
files can be constructed easilly.  Personally I would look into using java to 
create an applet that uses jdbc to get the files from the rdbms and then uses 
regular java libraries to "ftp" it.  Stream to stream essentially.  The files 
extracted from the rdbms never need to exist on the fs, only in memory.

The application for which I have an immediate requirement actually uses
postgres *and* files.   the files are required because of stupid
external reasons, they are collected and FTP'd to another system beyond
our control.   I'm already intending to evaluate Slony-I for the
postgres replication.
