Your complaint seems to be coming from commit dc788668, so the most
direct answer would be to make that configurable to the old behavior,
not to invent a new timeout behavior.
If I understand correctly, you are doing PITR from an archive, right?
So would restore_command be a reasonable place for the timeout?
And can you provide some approximate numbers to help me understand
where the timeout would be helpful? E.g. you have W GB of WAL to
replay, and restore would take X minutes, but some WAL is missing so
you fail after X-Y minutes, but if you has timeout Z everything would
be great.

Right, it's possible to do, but I think there's room for improvement so
we don't have to always scan the WAL. I'm getting a bit off-topic from
your proposal though. I'll bring it up in another thread when my
thoughts on this are more clear.
