Can you please try to finish the remaining work of the patch (I am bit
tied up with some other things)? I think the main thing apart from
representation of map as one-byte or one-bit per block is to implement
invalidation. Also, try to see if there is anything pending which I
might have missed. As discussed above, we need to issue an
invalidation for following points: (a) when vacuum finds there is no
FSM and page has more space now, I think you can detect this in
RecordPageWithFreeSpace (b) invalidation to notify the existence of
FSM, this can be done both by vacuum and backend.
