The thing to do here is modify pg_operator.dat and give both of these
operators an "oid_symbol". Perhaps Int4NegOperator is ok.  (I think
Int4UnaryMinusOperator might be on the verbose side.).  The code that
parses pg_operator.dat will then define that constant in
pg_operator_d.h.  You can then use that and the other ones you defined
for the numeric operator instead of hard coding the Oids in the patch.
