I've replaced P1 definition with a star sign. However, I don't like your second
proposal. The OP_Function has this interface to be basically-compatible with
legacy OP_BuiltinFunction opcode. Thus it is possible to care only about
opcode generation don't thinking about arguments order:
+ int op = func->def->language ==
+ FUNC_LANGUAGE_SQL_BUILTIN ?
+ OP_BuiltinFunction0 : OP_Function;
