Re: log ssl mode with connections?

I just turned on SSL for a test server and noticed that SSL mode isn't
logged with the connection. Should it be? It should be relatively simple
to add.

If I am allowing both SSL and non-SSL I might like to know which is used
by a particular connection.

Other places I've heard people ask for this info:

1) pg_stat_activity to see who's currently connected and how.

2) Via a function (boolean am_i_using_ssl()) so they can make security
decisions in views or procedural code.

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.

Anyone making those kind of decisions probably wants a generic
"connection is encrypted" flag. It could be true if a GSSAPI
connection has negotiated use of a security layer.

Of course I don't have my GSSAPI patches working as well as the SASL
ones were yet, and I haven't started on adding security layers yet
either.
