I don't think it's easy to create a single GUC because OpenSSL has
different APIs for both. So we'd have to add some custom parsing for
the combined string, which is likely to cause some problems imho. I
think separating them is the best option from the options we have and
I don't think it matters much practice for users. Users not familiar
with TLS might indeed be confused, but those users shouldn't touch
these settings anyway, and just use the defaults. The users that care
about this probably already get two cipher strings from their
compliance teams, because many other applications also have two
separate options for specifying both.
