libpq-fe.h is pretty clear on this matter:
/* Get the OpenSSL structure associated with a connection. Returns NULL for
* unencrypted connections or if any other TLS library is in use. */
extern void *PQgetssl(PGconn *conn);
We are under no compulsion to emulate OpenSSL if we switch to another
library. The design intent is that we'd provide a separate function
(PQgetnss?) and callers that know how to use that library would call
that function. If they don't, it's not our problem.
