* invoke check_expression() for all vcol_info's in mysql_prepare_create_table() to check for FK CASCADE * also check for SET NULL and SET DEFAULT * to check against existing FKs when a vcol is added in ALTER TABLE, old FKs must be added to the new_key_list just like other indexes are * check columns recursively, if vcol1 references vcol2, flags of vcol2 must be taken into account * remove check_table_name_processor(), put that logic under check_vcol_func_processor() to avoid walking the tree twice
