Is the Postgres Association part of smile.amazon.com?

Is the "United States Postgresql Association" a member of Amazon's charity
donation program through smile.amazon.com?

I ask because I've selected it as my charity of choice (it's actually an
option), and while I've generated some bit of money through my purchases,
Amazon says nothing has actually been donated.

They indicate that one reason could be that while Amazon knows about the
charity, the charity isn't actually registered.

If this is case, y'all might consider working out how to do that via
https://org.amazon.com/. I don't know how painless the charity
registration process is, but it's pretty painless for an Amazon shopper
(like myself) to transparently donate via smile.amazon.com. Maybe y'all
have already decided this isn't a thing you want to be involved in?

Anyways, I wanted to ask. Amazon has donated something like $46M to
charities since February this year, and it'd be cool if some of that went
to Postgres.

Thanks for your time and consideration!
