It's not very clear what you're trying to do here.
So, by "pid returns empty", you mean that the UPDATE updates 0 rows,
and you always expect it to update 1 row? The UPDATE is going to
update 0 rows if either "s" is an empty relation, or there's no row in
"area" with the "pid" that's in "s". "s" will be an empty relation if
"test" does not have any row matching WHERE area = 'test5'.
