| 14:27 | If an error occurs while writing to the database file during a VACUUM, discard the contents of the in-memory cache. This is required as if the database is a zipvfs database, the contents of the cache may be inconsistent with respect to the database as stored on disk. check-in: 07159e84 user: dan tags: trunk | |
