Sorry, Bill, I wasn't clear enough - I was suggesting writing a pl/pgsql
function something like this (not tested):
create function do_copy(path text) returns void
as
$$
begin
execute 'copy your_table from ' || filepath;
return;
end;
$$
language plpgsql;
EXECUTE in pl/pgsql is different from the version you refer to
above....here it is in the docs:
