Doing so can lead to an inconsistent copy of your database +into Postgres. +To avoid accidental error, the script will check that SQLite's `auto_vacuum` mechanism +is disabled, but the script is not able to protect against a manual `VACUUM` operation +performed either by the administrator or by any automated task that the administrator +may have configured. + Note that the database may take up significantly more (25% - 100% more) space on disk after porting to Postgres. |
