No, what's invalid is that using an unadorned 0 is understood as a "null pointer" by the compiler. That would happen in a lot of places except on a variadic function. However, the platform may define NULL as it wishes, and indeed in our c.h it is defined (conditionally) as (void *)0. If the platform had such a definition then it would work without issues. I assume the platform in question does something like #define NULL 0 which would be silly. -- Alvaro Herrera http://www.advogato.org/person/alvherre "El conflicto es el camino real hacia la unión" ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
