> I believe that pre7-3 SSL clients will work in 7.3.1, or am I wrong?

In 7.3 the SSL protocol switched from SSLv2 to TLSv1. If the server
method is switched to SSLv23_method it will be backwords compatable with
pre-7.3 clients without sacrificing the added security of TLSv1 for
newer stuff. There's been a lot of other changes to the SSL code between
7.2 and 7.3, but I've tested this out and haven't found any problems.
I've included a patch to src/backend/libpq/be-secure.c if you're
interested.
