I haven't been able to find anywhere, easily, in the documentation using google where a list of allowed data types for primary keys is. So, UUIDs can be primary keys? Any issues wtih them on sorting or paging of index tables, etc.? Also, the documentation says that UUIDs are 128 bit value, but never explicitly says that's how it's stored. Nor does it use one of the nice, blue headered tables for UUID (or ENUM) showing storage and other attributes as it does for numeric, character,boolean, date/time, binary, monetary, geometric, or network types.
