Yep.. i have solved this problem by specifying
the correct return type and variable type (should be the same)

but as said, in some cases pl_exec executes with type conversion.
as real example - i have :

return type = SETOF new type  "category_node(catid, pcatid)"
variable = R, SR -> RECORD

and

FOR R IN select * from ...
LOOP
   RETURN NEXT R;  /* add  RECORD to SETOF_of_CATEGORY_NODE */
....

and works...
the problem seems is teh same - on altered tables there is some porblem 
with this :)

Actualy - return type & variable in "RETURN NEXT" must be the same type.

// Solved
