As you may have noticed, I committed this (after some more cleanup). Of course, feel free to still review it, and please point out any issues you may find.
This comment on top of XLogRecordAssemble is not adapted as page_writes_omitted does not exist. Perhaps this is a remnant of some older version of the patch?
* If there are any registered buffers, and a full-page image was not taken * of all them, *page_writes_omitted is set to true. This signals that the * assembled record is only good for insertion on the assumption that the * RedoRecPtr and doPageWrites values were up-to-date. */ --
