Attached latest version patch. I updated the followings since the
previous version.
* Support vacuum progress reporting.
* Enable to set the parallel vacuum degree per table for autovacuum (0
by default)
* Fix bugs
I've done implementation of all parts that I attempted to support, so
this patch now is no longer WIP patch. Please review it.
