= New Features
* Spatial index creation syntax has been extended. Spatial index syntax now allows for columns before and after the z_order_lat_lon(...) part of the definition, but only for table indexes.
* RENAME in ALTER TABLE support was added.
* Allow z_order_lat_lon(...) syntax in conjunction with qualified column names.
* Set begin & end offsets in statement nodes in a statement list. This allows caller to know where one statement ends and another begins in the string it passed, for error reporting, logging, etc.
