Primary key generation is a known issue quite efficiently though not ideally solved by sequences. There are still problems with distributed generation, real uniqueness and predictability. Initially, UUID was not intended for use as a DBMS key, but its new versions (6, 7 and 8) make it quite convenient to use them as both synthetic and natural keys.
