Only true to the extent that you have cast a generic pointer to the
correct type to begin with.  However, we've probably wasted more time
arguing the point than it's really worth.

I would suggest leaving off the final semicolon in the macro definition
so that you can write

typedef struct RangeTblEntryRelation
    /* Fields valid for a plain relation RTE */
    char       *relname;        /* real name of the relation */
    Oid         relid;          /* OID of the relation */

Without this, tools like pgindent will almost certainly mess up these
struct declarations (I know emacs' C mode will get it wrong...)
