Brief overview of plans over the next month:

There are two patches available now that are essential to Hot Standby.
* Infrastructure Changes for Recovery (recovery_infrastruc.v8.patch)
* Subtransaction Commits and Hot Standby (atomic_subxids.v4.patch)

Other patches will be coming soon, probably in 3 phases:
* connect, take snapshots, run queries
* block locking - allows active WAL recovery while queries in progress
* DDL locking - allows replay of relation locks during recovery

All help given so far has been greatly appreciated. Further input,
reviews and assistance will be essential. Many thanks.
