Just ignore 00000001. Recovery will work fine even if absent. Don't
ignore all history files though, just that one. Hmmm, come to think of
it, why is it requesting it at all? We should just skip that request.

Well, that should at least generate a message that says "history file
empty, using targetTLI".

The timeline history file is only required when you do a recovery of a
system that has itself already undergone a PITR.

Have a look at pg_standby, accessible via CVS in contrib/pg_standby.
