Thanks!

Hm. That's a good point. I'm not exactly sure how the ripcord
allocator being used in Postgres combined with the asan
poison/unpoison calls would actually appear to lsan. But even aside
from that I believe there are allocations that are made early in
server initialization that are never freed and it's considered not
worth the book-keeping to free them due to the on-off nature of the
initialization.
