Here is my comment added to the top of the code.  Is it correct?

 * 	parse function
 * 	This code is confusing code because the database can accept
 *  relation.column, column.function, or relation.column.function.
 *  It can also be called as func(col) or func(col,col).
 *	Funcname is the first parameter, and fargs are the rest.
ParseColumnOrFunc(ParseState *pstate, char *funcname, List *fargs,
				  bool agg_star, bool agg_distinct,
				  int precedence)
