PostgreSQL supports left unary, right unary, and binary operators. Operators can be overloaded.
At least one of LEFTARG and RIGHTARG must be defined. For binary operators, both must be defined. For right unary operators, only LEFTARG should be defined, while for left unary operators only RIGHTARG should be defined.
Note: LEFTARG = Left type; RIGHTARG = Right type.
