A problem presentaion about ECPG, DECLARE STATEMENT

Dear ALL,

I want to report and consult about DECLARE STATEMENT.
This feature, committed last February, has some bugs.

* This is not thread-independent.
* If some cursors are declared for the same SQL identifier, 
  only one cursor you declared at last is enabled.
* This syntax does not have oracle compatibility.

In order to modify bugs, I think many designs, implementations, 
and specifications should be changed.
Any operations will be done at the preprocessor process, like #define
macro in C.

It will take about 2 or 3 weeks to make a patch.
Is it acceptable for PG12?

Best Regards,
