Hmmm. not really. Yet, more puzzles are there, so may be they'll guide
me to the answer, eventualy.
One thing I've spotted there, is that earlier I've naively assumed, that
when I define a RULE INSTEAD, the original query is "discarded" on the
final rewritten query. The example found at your link shows that it
isn't ... which is *extremally* strange, but somehow explains what I get
in my set of rules "supposedly" exclusive.
... or may be this "theory" is also wrong :(
Anyway, thenx for the link.
