Обсуждение: How to refer to standard functions?

Is there any way to refer to standard functions when defining new functions? I
tried " AS '-','int4eq' " but it just said "ERROR: could not access file "-":
No such file or directory".

It seems like a lot of data types would find it convenient if they have a
representation that is similar to one of the standard data types.

Sure, but they're language INTERNAL, not C.
