You need to roll in a backup I am afraid, and you should always have
some. Postgres has no way to replay back directly WAL records, it can
only forward replay. In such circumstances standby nodes with a delay
when applying WAL are useful.

By the way, this is not a bug. Such basic questions had better be
asked on pgsql-novice.
