Well, this just means a different piece of SQL needs to be sent for a
command depending on the server version, right? It's not like that's
tremendously different. The nice thing about most \X commands is that
they embed everything they need in a bunch of SQL, and they don't need
much else in C code. So it's not all that difficult.
And for commands that have been added later, an initial version could
just say "this server version does not support this command". It would
be already a huge improvement.
Probably the biggest change would be to support versions that did not
have schemas, but I think it would be OK to punt on that. We already
stopped supporting 7.2 anyway.
