Hi,

Here's the patch with the suggested format ; plus, I add some note in
the documentation about recovery_target_timeline, because I don't get
how strtoul(), with the special 0 base parameter can work without 0x
prefix ; I suppose that nobody use it.

I also change pg_controldata and the usage of this output by pg_upgrade.
I let internal usages unchanded : content of backup manifest and content
of history file.

Should I open a commitfest entry, or is it too soon ?

regards,
