I'm preparing new release of uniqueidentifier datatype. In new relaease
in addition to existing btree operator class I've implemented hash
operator class. But what class should be default for this datatype?
Uniqueidentifier is used for identification, so main operation with it
is '=', on machines with /dev/urandom '<','>' operations have no meaning
(parts for date and time are randomized). May be hash operator class
should be default for uniqueidentifier?
