In general, I'd need to go throught the pg source code which will take
some time. For instance, I wanted to see which are the requirements for
a patch to be accepted.

Currently, I can't provide you with a patch anyways (lack of time and
knowledge). However, I can possibly give it a try in a few weeks.

If someone is working on that in the meantime, please let me know.
