This claim is, to be frank, pretty astonishing. Can you produce a
self-contained test case to demonstrate that there's a leak?

I doubt that that proves anything at all. Such a function can't tell
whether libpq is holding onto memory internally. If you see growth in
memory usage over repeated query cycles, then it would be interesting.
