Two notes after looking at this quickly during the advanced patch
feedback session:
1. I would maybe split 0003 into two separate patches. One to make SET
UNLOGGED fast, which seems quite easy to do because no WAL is needed.
And then a follow up to make SET LOGGED fast, which does all the
XLOG_FPI stuff.
2. When wal_level = minital, still some WAL logging is needed. The
pages that were changed since the last still need to be made available
for crash recovery.
