- Each unlogged table, and each index on an unlogged table, has an initialization
- fork. The initialization fork is an empty table or index of the appropriate
- type. When an unlogged table must be reset to empty due to a crash, the
- initialization fork is copied over the main fork, and any other forks are
- erased (they will be recreated automatically as needed).
