GnuTLS support would mean that Debian could finally link psql against
libreadline (instead of just LD_PRELOADing it at runtime) because
there's not OpenSSL license conflict anymore. But I'm only going to do
that switch if there's no visible incompatibilities for clients, and
even any server-side GUC name changes would need a damn good
justification because they make upgrades harder. The LD_PRELOAD hack
in psql works, there's no pressing urgency to remove it.
