fix_high_availability_doc.patch (application/octet-stream) patch

Hi,

The following sentence in high-availability.sgml is not true:

    The background writer is active during recovery and will perform
    restartpoints (similar to checkpoints on the primary) and normal block
    cleaning activities.

I think this is an oversight of the commit 806a2ae in 2011; the
checkpointer process started to be responsible for creating
checkpoints.

I've attached the patch.

Regards,
