I would definitely be fine with --html (which indeed already exists) & 
--json (which does not, but could some day) as long options.

ISTM that it is more or less the case if an option simply presets a bunch 
of existing table output options which is an existing framework.

If there is a possible disagreement on one option, then let it out and use 
the corresponding short option if needed?

Tuple only:

   psql --csv -t -c 'TABLE foo' -o foo.csv

With title headers:

   psql --csv    -c 'TABLE foo' -o foo.csv

Would be okay.
