Hmmm... I also would be interested in having a trigger run a shell or
python script, but didn't really see anything in the documentation that
indicated how to go about this.  I would appreciate any pointers on
where to go for more info.

Basically, I run a dialup server which logs uploads to a PostGres
table.  I would like the logging of an upload "trigger" an external
program that further processes the uploaded file based on the uploader
information.
