Can you switch to int4 or int8 instead of NUMERIC(12)? I think that
we don't currently consider NUMERIC hashable, and you really need a
hash subplan here. In general NUMERIC is a bad choice if you're hot
about performance, anyway. Integers or floats would be probably two
orders of magnitude faster.
