Hi,
I'm writing a Postgres native extension and I would like to check that a
numeric is zero.
My problem is that all exported methods like numeric_eq or numeric_sign
require me to have a numeric to start with, and const_zero is not exported
in numeric.c.
Any idea how to check it?
Thanks
Gabriel
Hi Ken,
Thanks a lot, that's a cool idea and I think that it will cover my needs.

Hello,
I'd like to convert a string number to a number being able to provide the
custom format.
With dates it works perfectly fine, so that I can do:
SELECT to_date('18 09 10', 'YY MM DD')
Is there something similar with numbers?
SELECT to_number('9,000', some_format) = 9;
SELECT
