We've never promised that psql's backslash commands would work at all
with older backends, so I think removing compatibility with pre-7.3
backends at this point isn't a problem. OTOH, going out of your way
to remove compatibility seems a bit pointless, so I'd vote against the
"have_query" parts of this patch. Just change the output format.
