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. 5. Promote standby B. 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.
