With our current PRNG infrastructure it doesn't cost much to have
a separate PRNG for every purpose. I don't object to having
array_shuffle() and array_sample() share one PRNG, but I don't
think it should go much further than that.
Thanks for your thoughts, Tom. I have a couple of questions. Should we
introduce a new seed function for the new PRNG state, used by array_shuffle()
and array_sample()? What would be a good name? Or should those functions use
pg_global_prng_state? Is it safe to assume, that pg_global_prng_state is
seeded?
I'd suggest to use the existing global state. The global state should be
seeded at the process start, AFAIKR.
