> Got it, but if other people don't agree then this is going nowhere. Yes. As I wrote, I don't particularly care about functions like "is point on line". I can prepare a patch to fix as many problems as possible around those operators by preserving the current epsilon.
I though we were arguing about *all* operators. Having containment and placement operators consistent with each other, is the primary thing I am trying to fix. Is removing epsilon from them is acceptable? We can also stay away from changing operators like "~=" to minimise compatibility break, if we keep the epsilon on some places. We can instead document this operator as "close enough", and introduce another symbol for really "the same" operator. That said, there are some places where it is hard to decide to apply the epsilon or not. For example, we can keep the epsilon to check for two lines being parallel, but then should we return the intersection point, or not? Those issues may become more clear when I start working on it, if preserving epsilon for those operators is the way to go forward. -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
