Re: Column labels with --full

I think it doesn't make much sense to combine --full and an aggregate
operation. SQL databases (Except for sqlite) give an error when you
try to use a non grouped column outside of an aggregate function; this
is the same situation.

Maybe document it as deprecated, print a warning about the
combination, and turn it into a full blown error in a few releases?
