There are a couple of threads about issues with uuid-ossp (AIUI it's
abandonware at this point). If PostgreSQL had a proper PRNG with a
128-bit state it could just implement uuid_generate_v4() function in
core and most people could probably drop uuid-ossp.

I have a branch[1] which implements uuid_generate_v4 in core using
pg_lrand48, but since it only has 48 bits of state it's probably not an
acceptable replacement for uuid-ossp for now.

Is anyone working on a new PRNG for PostgreSQL at the moment?
