Hi all,

I did a rebase for the patch to v8 and incorporated a few changes:

1) Updated documentation, added new tests, and applied minor code
adjustments based on prior review comments.
2) Tweaked the initialization of waitReplayLSNState so that
non-backend processes can call wait for replay.

Started a new thread [1] and attached a patch addressing the polling
issue in the function
read_local_xlog_page_guts built on the infra of patch v8.

Feedbacks welcome.

Best,
Xuneng
