   Another possibility is a nice table:
   ```
   +--------------+------------------------+-----------------+
   | Page kind    | RLE-encoded data kind  | Prepend length? |
   +--------------+------------------------+-----------------+
   | Data page v1 | Definition levels      | Y               |
   |              | Repetition levels      | Y               |
   |              | Dictionary indices     | N               |
   |              | Boolean values         | Y               |
   +--------------+------------------------+-----------------+
   | Data page v2 | Definition levels      | N               |
   |              | Repetition levels      | N               |
   |              | Dictionary indices     | N               |
   |              | Boolean values         | Y               |
   +--------------+------------------------+-----------------+
   ```
