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?
