You should be able to knock up a simple script in bash, perl or python
to do what you want.

Sort of like:

Use 'psql' to get a list of the databases
Sanitize the list.
Loop through the list doing backup.
At the end zip them all.

With a little bit of trickery you should be able to zip them as you go.

With regards being too close to the system, while this is true, it
also possible to be distant from the system's entrails and not don't
realize the implications and difficulties of your brilliant idea for
enhancement!
