Looks reasonable except for one nitpick: the "out of range" message
in the ERANGE case should be kept mentioning real, not the passed
type_name, to be equivalent to the way float8in_internal does it.
I lack enough caffeine to recall exactly why float8in_internal
does it that way, but the comments are exceedingly clear that it was
intentional, and I'm sure the same rationale would apply here.
(float8in_internal also goes out of its way to show just the part of
the string that is the number in that case, but I'm willing to let
that pass for now.)
