Half a dozen interrelated GUCs to control a single command fairly
screams "bad design" to me; especially the ones that specifically bear
on the command semantics, rather than being performance settings that
you could reasonably have system-wide defaults for. Could we please
look at doing it via COPY options instead?
It might be time to switch COPY over to a more easily extensible
option syntax, such as we just adopted for EXPLAIN.
