I agree with this wholeheartedly. 1 item on the ground should be 1 item
in the database. What no one else has suggested is that if you really
need to put something in the DB twice, then at least use a relationship
to link the DB objects together.

I expect that someone with PostGIS knowledge can construct a query to
quickly identify all the parking nodes inside parking areas and produce
a list. I'm sure that many of us could write a perl or python script to
take this list and delete or relate the nodes.
