Currently, libpq client code must have a connection handle before it can query the "library" SSL attribute. This poses problems if the client needs to know what SSL library is in use before constructing a connection string. Allow PQsslAttribute(NULL, "library") to return the library in use -- currently, just "OpenSSL" or NULL. The new behavior is announced with the LIBPQ_HAS_SSL_LIBRARY_DETECTION feature macro, allowing clients to differentiate between a libpq that was compiled without SSL support and a libpq that's just too old to tell.
