I think I see the problem in hash_xlog_vacuum_get_latestRemovedXid().
It seems to me that we are using different block_id for registering
the deleted items in xlog XLOG_HASH_VACUUM_ONE_PAGE and then using
different block_id for fetching those items in
hash_xlog_vacuum_get_latestRemovedXid(). So probably matching those
will fix this issue (instead of fetching block number and items from
block_id 1, we should use block_id 0).
