generation.
-uuid_v3(uuid, text)
+uuid_v5(uuid, text)
returns a version 5 uuid using the supplied namespace uuid and the
given input string. This is an sha1 based uuid.
Numeric: treats the UUID as a 128 bit number and converts it to a numeric.
Bit(128) and bit varying: treats the uuid as a 128 bit vector.
+Casts to bit(n) where n is shorter than 128 will truncate
+the uuid. Where n is longer than 128, the bit vector
+will be zero extended.
