This function provides a way of generating version 4 (pseudorandom) UUIDs based on pgcrypto's PRNG. The main reason for doing this is that the OSSP UUID library depended on by contrib/uuid-ossp is becoming more and more of a porting headache, so we need an alternative for people who can't install that. A nice side benefit though is that this implementation is noticeably faster than uuid-ossp's uuid_generate_v4() function. Oskari Saarenmaa, reviewed by Emre Hasegeli
