Oops. Thank you. Noted.

I think the previous additional digits behavior still exist
in the latest patch. For example:

=# set extra_float_digits = 0;
SET
=# select float4in('1.123456789');
float4in
----------
1.12346
(1 row)

=# set extra_float_digits = 1;
SET
=# select float4in('1.123456789');
float4in
-----------
1.1234568
(1 row)

The extra_float_digits is increased by 1, but two digits are
added. Without the patch, it will render ' 1.123457' instead.
