## How to upgrade PostgreSQL ?
We use the PostGIS extension to hold the geospatial data. Migrating to a new major PostgreSQL version (with `pg_upgradecluster`) is not supported when there's also a PostGIS upgrade.
For instance migrating from Debian Buster (10) to Bullseye (11) upgrades PostgreSQL from 11 to 13, but also Postgis from 2.5 to 3.1, so you won't be able to perform a simple upgrade.
In this case, it's better to:
* Dump the database (with `pg_dump`) from the old PostgreSQL cluster.
* Stop the old cluster.
* Create and start the new one (if not already done when upgrading the system).
