Sorry guys, I'm busy with WAL issues currently.
CRC will require initdb, so it's better to implement it
first...
Also, is TOAST-table vacuuming fixed now?

Still broken.  Hiroshi had muttered something about fixing the internal
commit of VACUUM so that it's more like a real commit --- including
advancing the transaction ID --- but still doesn't release the exclusive
lock held by VACUUM.  Basically we need to propagate the locks forward
to the new xact instead of releasing them.  I think that would be a nice
clean solution if we could do it.  Do you have any ideas about how?

Can someone please remind me?  CRC allows us to know of WAL log is
corrupt?

There are two uses for CRC in connection with the WAL log 
("write-ahead log log").  First, it helps to reveal corruption 
in the log.  Second, it makes it possible to identify the end of 
the log when the log lives on a raw partition.
