But wouldn't it suffice to issue the "old" versions of the command
queries on an "old" server? It shouldn't be that hard to keep backward
compatibility among minor versions of psql. Even the server version is
known... They're just queries, right? How hard can it be to keep various
versions around so as to match the server version?
I can understand that new psql client features wouldn't be backward
compatible, but normal commands like \d should keep working.
