Another reason to always keep all the database processing and retrieving 
logic on the PG server. Rather than link to a PG table in your form, do 
a pass-through PG SELECT .... FROM <table> and link to the result table.

You're going to spend a lot of unfruitful time trying to get direct 
linking working and when you finally separate Paradox and Postgres with 
pass-through SQL that time will have been wasted. Grit your teeth and 
separate the two now. You'll be glad you did. Performance for one.
