Hm, the actual bug report hasn't come through yet, but I gather your
point is that float8_regr_combine hasn't gotten the word about the
efforts we've made in float8_regr_accum to avoid roundoff error for
all-the-same inputs. Good point, but isn't it also missing the latter
routine's recently-added logic for forcing outputs to NaN when
necessary?
Also, TBH, the proposed comments read like AI slop; they don't
address any of the questions I had on first reading the patch.
Some more effort seems appropriate there.
