Well, if we wanted to *require* a heading row in CSV mode, it would be
relatively foolproof. What I don't like is the proposal for an
independent option; you've got a 50-50 chance of getting it wrong on
import, and that's too high odds for me.
Next question: are you imagining that the header row will actually have
any semantic significance on input? Will we check the column names?
Will we be willing to rearrange the columns if the header row claims the
column order is different than the COPY command says?
