Welcome to the community!

I apologize for not being more clear.

Here, it is customary to send a patch rather than a web link when one
has code one wishes to share. This is for several reasons:

1. To establish that you are warranting that you have the right to
send the patch, i.e. that it is not legally encumbered in some way.

2. To ensure that the patch stays in the archives, as large web sites
have gone away in the past, and will in the future.

3. Because this is how the current development process works.

When I mentioned documentation, I was referring to the operation of
the SQL-callable interface, assuming that there is one. When people
apply the patch, they need to have some idea what it is supposed to do
and how to make it do those things. Any difference between what it is
supposed to do and what it actually does a bug, whether in the
implementation, the documentation, or both.

These things and many others are in the

Best,
