After testing with the new patch, the following problems are observed.
Defect - 1:
1. start primary A
2. start standby B following A
3. start cascade standby C following B.
4. start another standby D following C.

6. After successful time line switch in cascade standby C & D, stop D.
7. Restart D, Startup is successful and connecting to standby C.
8. Stop C.
9. Restart C, startup is failing.
Defect-2:
1. start primary A
2. start standby B following A
3. start cascade standby C following B.
4. Start another standby D following C.
5. Execute the following commands in the primary A.
create table tbl(f int);
insert into tbl values(generate_series(1,1000));
6. Promote standby B.
7. Execute the following commands in the primary B.
insert into tbl values(generate_series(1001,2000));
insert into tbl values(generate_series(2001,3000));
8. Stop standby D normally and restart D. Restart is failing.
9. Stop standby C normally and restart C. Restart is failing.
Note: Stop the node means doing a smart shutdown.
