Tom Lane d4f109e4a2 Doc: update description of random() function.
Commit 3804539e4 neglected to update the documentation's claim that
random() uses a "linear congruential algorithm".  In hopes of avoiding
the same mistake if someone replaces our PRNG again, just say it's a
deterministic 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: 3804539e4's commit message
really should have mentioned that the random() sequence after
setseed(), while still repeatable, will differ from what you got
in pre-v15 releases.
