Hi Thomas,

It depends what you are trying to do. GROUP BY functionality is supplied
by PostgreSQL rather than PostGIS, and both projects are written in C.
If you can explain in more detail what you are trying to do, I'm sure
people on the list can point you in the right direction.


Kind regards,

Mark.
