Hmmm ... I'm not aware of any memory leaks in libpq, but that doesn't
mean there are none. Of course, if you're forgetting to PQclear()
some PGresults, that's not libpq's fault ;-).

No. At least, I see no setenv() calls in it, and I think that it'd
be pretty unfriendly for a library to do that to its host application.

backend/libpq is unrelated to interfaces/libpq. (I've seen hints
that they arose from a common code base, but if so, that was a
few decades and a lot of rewrites ago.)
