Hi

Is there some reason why \copy statement (parse_slash_copy parser) doesn't
support psql variables?

I remember wondering about that when I was working on the \if stuff. I dug
into it a bit, but the problem was out of scope for my goals.

The additional options recently added to \g reduced my need for \copy, and
it seemed liked there was some effort to have input pipes as well, that
would eliminate the need for \copy altogether.
