First of all, thank you all for working on this feature.

Sorry for chiming in so late here, but I was a little surprised to see the
TLS version in the GUC name.  ISTM this would require us to create a new
GUC for every new TLS version, or explain that ssl_tls13_ciphers isn't just
for 1.3.  Perhaps neither of those things are too terrible, but I felt it
was worth bringing up.
