The patch looks good overall.  It applies cleanly and passes all tests.

One question.  Do we want to create this file all the time (as written),
or only when archive_mode = always?

It appears that CleanupBackupHistory() will immediately remove the
history file when archive_mode != always so it seems useless to write
it.  On the other hand the code is a bit simpler this way.  Thoughts?
