The reason it was kept was to override the search path --- unqualified
NUMERIC will always be taken as pg_catalog.numeric even if you have some
other type "numeric" in front of it. I believe we had concluded that this
behavior is required by the SQL spec. In any case, it would be kinda
weird for DECIMAL to have that behavior and NUMERIC not.
