I think it makes sense to move "cache hash index meta page" first,
however "microvacuum support for hash index" is based on WAL patch as
the action in this patch (delete op) also needs to be logged.  One
idea could be that we can try to split the patch so that WAL logging
can be done as a separate patch, but I am not sure if it is worth.

You can start reviewing some of the operations like "Create Index",
"Insert".  However, some changes are required because of change in
locking strategy for Vacuum.  I am planning to work on rebasing it and
making required changes in next week.
