I don't see any way to not use a trigger given your requirement. And as
written I don't see that you need the second function - just write the
trigger function in plsh. Admittedly its probably better to have two
functions from an architecture standpoint.
Listen/Notify doesn't seem to make sense as you want the server to ensure
that the file exists - not some other client that may or may not be
connected.
