I am using docker compose to run Peertube (with the yml file). When I follow the update procedure from the help file, which is to delete the old conatiners and pull the new ones, I get the following error from the Postgres docker container:
PostgreSQL Database directory appears to contain a database; Skipping initialization 2021-04-18 15:46:25.137 UTC  FATAL: database files are incompatible with server 2021-04-18 15:46:25.137 UTC  DETAIL: The data directory was initialized by PostgreSQL version 10, which is not compatible with this version 13.2.
I guess I need to update the SQL database somehow.
Where can I find the procedures for that?
