Cool. I took a quick look through the code, and I think that a smoke
test could be made just by diking out these lines in
/* Don't bother requesting SSL over a Unix socket */
conn->allow_ssl_try = false;
Actual support would require rather more effort --- for instance,
I doubt that the default behavior should be to try to do SSL over a
socket, so "sslmode" would need some extension, and we'd want to extend
the pg_hba.conf keywords --- but I think this would be enough to allow
verifying whether it will work.
