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. David
