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,
