After some furtehr research I determined that it was ignoring the fieldTwo
check completely. I finally narrowerd it ddown because my code read
fieldTwo ALIAS FOR $2;
and the query read
SELECT .....fieldtwo = fieldTwo
And plpgsql was not being case sensitive and thought it was comparing it to
itself.
Take care,
