Simple question about Postgress rule system and docs for it .

Hello! 

  Its, may be ,little "gluk" in  doc, - sources and docs and examples
for Create Rule not correlated. Conctrento :))  ->       В доке ->CREATE RULE example_1 AS ON UPDATE  emp.salary WHERE
old.name= "Joe"      /*  ^^^ */    DO         UPDATE emp         SET salary = new.salary        WHERE emp.name =
"Sam";
/* ^^^ - its maby  type-bUg -> ON UPDATE TO )*/
And  in sources........      /* ----------       * The current rewrite handler is known to work on relation level
*rules only. And for SELECT events, it expects one non-nothing       * action that is instead and returns exactly a
tupleof the       * rewritten relation. This restricts SELECT rules to views.       *       *         Jan       *
----------      */      if (event_obj->attrs)              elog(ERROR, "attribute level rules currently not
 
supported");In result on  all query, where after  "ON"   we put  something as
"emp.salary" ,Postgres answer :ERROR: "attribute level rules currently not supported" But in docs  CREATE RULE name AS
ONevent    TO object [ WHERE condition ]    DO [ INSTEAD ] [ action | NOTHING ]..........
 
where --> object Object is either table or table.column.                            ^^^^^^^^^^^^^!!!!!  8-()И
