No. In general you can only use parameters in DML statements
(SELECT/INSERT/UPDATE/DELETE); utility statements don't cope,
mainly because most of them lack expression eval capability
altogether.
Perhaps the special case of COPY from a SELECT could be made
to allow parameters inside the SELECT, but I don't think
anyone has tried.
