Oh, I had not looked at the syntax closely.  I agree, that basically
sucks: it's overcomplicated and under-featured, because you can't
control the actual program command line very conveniently.  Nor do I see
a reason to force this into the model of "program filtering a specific
file".  What happened to the previous proposal of treating the COPY
target as a pipe specification, ie

	COPY table FROM 'some command line |';
	COPY table TO '| some command line';

Adding a pipe symbol to the target works exactly the same for \copy.
