I was thinking of hacking on postgres a bit. I want to start with filling out the operations list for data types that seem to be missing obvious operators.
In particular I'm thinking of things like . an aggregate function for cidr that would find the smallest enclosing netblock. . an aggregate function for box, point, etc for the bounding box I had some other ideas but I don't remember them now. Anyways, I'm a bit stumped where to start. Looking at the existing operations there seems to be a bit of magic using macros involved in creating accumulators and result sets that I don't get. Is there a walk-through of a typical datatype and how to code an operator somewhere? -- greg ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
