The use of the PostgreSQL engine is optional.
However, if the engine is deficient or not installed, some functionalities will be inaccessible or will no longer be provided
- Personal categories:
If you use your own categories, the PostgreSQL engine can store a large amount of data, i.e. millions of websites ordered by theme.
- Statistics: Access statistics (HTTP or DNS) use the SQL engine.
- Fingerprinting Web Access:
Web access control through fingerprinting stores fingerprints and rules inside the PostgreSQL engine.
¶ Backup and restore
By default, the database is exported to a backup file every day at 05:50, with a retention of 3 backup sets.
This lets you restore yesterday’s data in case of an issue.
