Hello

I read the code and test the patch, it run well on my side, and I have several issues on the

patch.

1. When call RequestXLogStreaming() during replay, you pick timeline straightly from control

file, do you think it should pick timeline from timeline history file?

2. In archive recovery mode which will never turn to a stream mode, I think in current code it

will call RequestXLogStreaming() too which can avoid.

3. I found two 018_xxxxx.pl when I do make check, maybe rename the new one?
