A few changes:

- Improve COPY performance (Alon Goldshuv)
- Optimize the locking used by sequential scans (Qingqing Zhou)

- Re-enable full_page_writes (Tom)
This flag can now be used even with PITR. It is turned **on** (not off!)
automatically between pg_start_backup() and pg_stop_backup() calls.

- Add support for forcing a switch to a new xlog file (Simon Riggs)
...should include Tom

- Improve performance of replaying WAL logs on a backup server (Simon
Riggs)
...I describe this as Restartable Recovery... don't think it improves
performance exactly, just avoids needing to re-run it from scratch

My memory says this was eventually removed, even though it was committed
for a time. Am I wrong?
- Make EXPLAIN sampling smarter, to avoid excessive sampling delay
(Martijn van Oosterhout)
