Well of course that's not entirely up to me, but I was hoping to
commit it for PG13.
It's very well covered by a large number of regression tests in both
numeric.sql and numeric_big.sql, since nearly anything that calls
ln(), log() or pow() ends up going through sqrt_var(). Also, the
changes are local to functions in numeric.c, which makes them easy to
revert if something proves to be wrong.
