I've read through the patch, and that's pretty cool.
-static void

In 0001, should the comment describing this routine be updated as
well?

This is missing a <filename> markup here.

Perhaps a couple of <literal>s here.

Shouldn't these two checks be reversed? And is there actually a need
for the first check at all knowing that the version callback should be
in charge of performing the validation vased on the version received?

Not sure that it is a good idea to duplicate this pattern twice.
Shouldn't this be something we'd want to control with an option in the
init() method instead?

Relying both on controlpath, being a full path to the control file
including the data directory, and context->backup_directory to read
the contents of the control file looks a bit weird. Wouldn't it be
cleaner to just use one of them?
