hi,
To avoid inserting duplicate checkpoints when the system is idle, the code of CreateCheckPoint make two tests to determine that nothing has happened since the start of the last checkpoint.
But because the layout of XLOG record was changed, the condition would never to be true. The attachment is the patch to fix it, thanks.
