-Migrating from MySQL/MariaDB to PostgreSQL
-==========================================
-
-Our recommended database for all production installations is PostgreSQL. Support for MySQL/MariaDB will be removed in
-pretix 5.0.
-
-In order to follow this guide, your pretix installation needs to be a version that fully supports MySQL/MariaDB. If you
-already upgraded to pretix 5.0, downgrade back to the last 4.x release using ``pip``.
-
-.. note:: We have tested this guide carefully, but we can't assume any liability for its correctness. The data loss
-          risk should be low as long as pretix is not running while you do the migration. If you are a pretix Enterprise
-          customer, feel free to reach out in advance if you want us to support you along the way.
-
-Update database schema
-----------------------
-
-Before you start, make sure your database schema is up to date::
-
-    # sudo -u pretix -s
-    $ source /var/pretix/venv/bin/activate
-    (venv)$ python -m pretix migrate
-
-Install PostgreSQL
-------------------
-
-Now, install and set up a PostgreSQL server. For a local installation on Debian or Ubuntu, use::
-
-    # apt install postgresql
-
-Having the database server installed, we still need a database and a database user. We can create these with any kind
-of database managing tool or directly on our database's shell. Please make sure that UTF8 is used as encoding for the
-best compatibility. You can check this with the following command::
-
-    # sudo -u postgres psql -c 'SHOW SERVER_ENCODING'
-
-Without Docker
-""""""""""""""
-
-For our standard manual installation, create the database and user like this::
-
-    # sudo -u postgres createuser pretix
-    # sudo -u postgres createdb -O pretix pretix
-
-With Docker
-"""""""""""
-
-For our standard docker installation, create the database and user like this::
-
-    # sudo -u postgres createuser -P pretix
-    # sudo -u postgres createdb -O pretix pretix
-
-Make sure that your database listens on the network. If PostgreSQL on the same same host as docker, but not inside a docker container, we recommend that you just listen on the Docker interface by changing the following line in ``/etc/postgresql/<version>/main/postgresql.conf``::
-
-    listen_addresses = 'localhost,172.17.0.1'
-
-You also need to add a new line to ``/etc/postgresql/<version>/main/pg_hba.conf`` to allow network connections to this user and database::
-
-    host    pretix          pretix          172.17.0.1/16           md5
-
-Restart PostgreSQL after you changed these files::
-
-    # systemctl restart postgresql
-
-If you have a firewall running, you should also make sure that port 5432 is reachable from the ``172.17.0.1/16`` subnet.
-
-Of course, instead of all this you can also run a PostgreSQL docker container and link it to the pretix container.
-
-Stop pretix
------------
-
-To prevent any more changes to your data, stop pretix from running::
-
-    # systemctl stop pretix-web pretix-worker
-
-Change configuration
---------------------
-
-Change the database configuration in your ``/etc/pretix/pretix.cfg`` file::
-
-    [database]
-    backend=postgresql
-    name=pretix
-    user=pretix
-    password=  ; only required for docker or remote database, can be kept empty for local auth
-    host=      ; set to 172.17.0.1 in docker setup, keep empty for local auth
-
-
-Create database schema
------------------------
-
-To create the schema in your new PostgreSQL database, use the following commands::
-
-    # sudo -u pretix -s
-    $ source /var/pretix/venv/bin/activate
-    (venv)$ python -m pretix migrate
-
-
-Migrate your data
------------------
-
-Install ``pgloader``::
-
-    # apt install pgloader
-
-.. note::
-
-   If you are using Ubuntu 20.04, the ``pgloader`` version from the repositories seems to be incompatible with PostgreSQL
-   12+. You can install ``pgloader`` from the `PostgreSQL repositories`_ instead.
-   See also `this discussion <https://github.com/pretix/pretix/issues/3090>`_.
-
-Create a new file ``/tmp/pretix.load``, replacing the MySQL and PostgreSQL connection strings with the correct user names, passwords, and/or database names::
-
-    LOAD DATABASE
-        FROM mysql://pretix:password@localhost/pretix  -- replace with mysql://username:password@hostname/dbname
-        INTO postgresql:///pretix                      -- replace with dbname
-
-    WITH data only, include no drop, truncate, disable triggers,
-         create no indexes, drop indexes, reset sequences
-
-    ALTER SCHEMA 'pretix' RENAME TO 'public'           -- replace pretix with the name of the MySQL database
-
-    ALTER TABLE NAMES MATCHING ~/.*/
-        SET SCHEMA 'public'
-
-    SET timezone TO '+00:00'
-
-    SET PostgreSQL PARAMETERS
-         maintenance_work_mem to '128MB',
-         work_mem to '12MB';
-
-Then, run::
-
-    # sudo -u postgres pgloader /tmp/pretix.load
-
-The output should end with a table summarizing the results for every table. You can ignore warnings about type casts
-and missing constraints.
-
-Afterwards, delete the file again::
-
-    # rm -rf /tmp/pretix.load
-
-Start pretix
-------------
-
-Now, restart pretix. Maybe stop your MySQL server as a verification step that you are no longer using it::
-
-    # systemctl stop mariadb
-    # systemctl start pretix-web pretix-worker
-
-And you're done! After you've verified everything has been copied correctly, you can delete the old MySQL database.
