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.
