| 12 # on the incremental vacuum feature. | |

| 15 # were made to: | |
| 16 # | |
| 17 # * Truncate the database after a rollback mode commit, and | |
| 18 # | |
| 19 # * Avoid moving pages to locations from which they may need to be moved | |
| 20 # a second time if an incremental-vacuum proccess is allowed to vacuum | |
| 21 # the entire database. | |
