Fix an old description in high-availability.sgml
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,

The <command>CHECKPOINT</command> command is accepted during recovery,
though it performs a restartpoint rather than a new checkpoint.

Good catch it is. Your phrasing looks good to me.
