Bug reference:      14803
Logged by:          bret shao

Operating system:   ubantu
Description:

when call KeepLogSeg to get the oldest xlog file in function
CreateRestartPoint,
I think the endptr shoule be the repalyPtr not the later one of receiverPtr
and replayPtr.endptr = (receivePtr < replayPtr) ? replayPtr : receivePtr;

Because that if the endptr is the receiverPtr, it means that may be the xlog
file that is being redo will be dropped.

if the file which is being needed in recover redo work is dropped then the
server will down.

i'm not very clear why use receiverPtr as the endptr to call
KeepLogSeg(endptr, &_logSegNo);
