Because this is the first time I can remember where *none* of the \ commands
work with older servers.  And because the error we give is pretty ungraceful.

Hmmm ... how difficult would it be to give a useful error message instead of a
SQL error?  Something like:

"I'm sorry, that PSQL command did not work.  Most likely, you are connecting
to a different version of PostgreSQL."
