- Fix the iq result sent at the end of a MAM response. Some clients (e.g.
gajim) would throw an error as a result.
+Sqlite3 to PostgreSQL migration
+If you used biboumi with the sqlite3 database backend and you want to
+start using postgresql instead, follow these simple steps:
+ - Make sure your Sqlite3 database has the correct format by running at
+ least biboumi version 6.0 against this database. Indeed: biboumi can
+ upgrade your database scheme by itself automatically when it starts, but
+ the migration process can only migrate from the latest known schema,
+ which is the one in version 6.x and 7.x. If you are migrating from
+ version 6.x or 7.x, you have nothing to do.
+ - Start biboumi (at least version 7.0) with db_name configured to use
+ your postgresql database: this will create an empty database, create all
+ the tables with all the rights columns, ready to be filled.
+ - Backup your database if you value it. The migration process will not
+ write anything into it, so it your data should theorically be kept
+ intact, but we never know.
+ - Run the dump script found in biboumi’s sources:
+ `<scripts/>`_. Its first and only argument must be the path
+ to your sqlite3 database. For example run `./scripts/
+ /var/lib/biboumi/biboumi.sqlite`. This will create, in your current
+ directory, some sqlite files that contain instructions to be fed into
+ postgresql.
+ - Import all the ouput files thusly created into your PostgreSQL, with
+ something like this: `psql postgresql://user@password/biboumi < *.sql`.
+ This takes a few minutes if your database is huge (if it contains many
+ archived messages).
