That information is available to the client in the form of the API call
PQgetssl(). It will return NULL if no SSL is in use, or something other
than NULL if it is (a SSL * pointer, but you don't need to know that if
you just want to know if you're on SSL or not).
IIRC it was originally disucssed to put it as a function callable, but
it was decided that it makes a lot more sense to provide it in the
client library. I don't know how many other client libraries provide the
SSL information stuff.
