Hi!

Here is an updated version of patch.
Major changes are:
- single out options to initialize cluster with given xid/mxid/mxoff into separate patch 0004 with a purpose of review and apply it separately before the main patch.
  We also created a separate CF entry to handle this [1].
- add unit tests for lazy page conversion from 32 to 64 bits xid format (inside patch 0008).
- make logical replication of xid format to be 64 bit and add test (inside patch 0008).
- remove unnecessary padding to compactify XLogRecord
- 32 to 64 bit page lazy conversion refactoring
- rebase to recent upstream branch

Patches 0001-0003 are identical to the v33 from Aleksander Alekseev in thread [2].


Reviews are very welcome!
