Doc: update description of random() function.
Commit3804539 neglected to update the documentation's claim thatrandom() uses a "linear congruential algorithm". In hopes of avoidingthe same mistake if someone replaces our PRNG again, just say it's adeterministic pseudo-random number generator and leave it at that.Anybody who really wants to know can look in the source code.COMPATIBILITY NOTE FOR RELEASE NOTES:3804539's commit messagereally should have mentioned that the random() sequence aftersetseed(), while still repeatable, will differ from what you gotin pre-v15 releases.Noted by Dagfinn Ilmari Mannsåker; wording suggestion by Dean Rasheed.Discussion:https://postgr.es/m/875ynfpiru.fsf@wibble.ilmari.org
