Sorry, kinda missed that. Anyway, there's no way for pg to know which
operation is gonna match. Without an index on it. So my guess is
that it just guesses some fixed value. With an index it might be able
to get it right, but you'll need an index for each type of match
you're looking for. I think. Maybe someone else on the list has a
better idea.
