Comment(by mmetz):

 Some comments on the patch:

 The patch makes sense to me and is indeed a substantial speed improval.
 However, partitions were confused with categories. The patch was written
 in C++ style, but the module is a C module. I made further changes to the
 patch: the attribute table of current vector is modified instead of
 creating a new vector, giving a further speed-up. The vector is opened
 without topology, that makes it easier for larger point clouds. Updating
 the database uses db_[begin|commit]_transaction(), giving a further speed-
 up.

 Thanks for your contribution!
