I think it's a worthwhile approach to pursue. But until it actually
fixes the problem of leaving around uninitialized pages I don't think
it's very meaningful to do performance comparisons.

Attached patch solves this issue, I am allocating the buffer for each page and initializing the page, only after that adding to FSM.

Few comments about patch:

! UnlockReleaseBuffer(buffer);
! RecordPageWithFreeSpace(relation, BufferGetBlockNumber(buffer), freespace);
