<!-- Greeting --> Hi @A-little-bit-of-data! 👋 I'm here to help you solve bugs, answer questions, and assist you while you wait for a human maintainer. Let’s tackle your PostgreSQL migration issue together! <!-- Answer --> I found a similar unsolved discussion regarding PostgreSQL not starting when using Helm install, which might be related to your issue. You can check it out [here](https://github.com/apache/superset/discussions/26961) <sup>[[1]](https://github.com/apache/superset/discussions/26961)</sup>. To address your specific concerns: 1. **Inconsistent PostgreSQL Versions**: The inconsistency in PostgreSQL versions between `superset/values.yaml` and `superset/charts/postgresql/values.yaml` might be due to different default configurations or updates in the Helm chart. It's important to ensure that the PostgreSQL version you are using is compatible with your data directory. Since version 16.1.0-debian-11-r25 works for you, you should continue using it. 2. **Migration Process**: When upgrading PostgreSQL versions, you need to ensure that the data directory is compatible with the new version. The error you encountered indicates a version mismatch. Here’s a general approach to migrate your data: - **Backup your data**: Use `pg_dump` to create a backup of your current database. Ensure that you are using the correct options to avoid errors during `pg_restore`. ```bash pg_dump -Fc -h superset-postgresql -p 5432 -U superset -d your_database_name > /tmp/superset_backup.dump ``` - **Restore your data**: After setting up the new PostgreSQL instance, use `pg_restore` to import the data. Make sure the target database is prepared to accept the data. ```bash pg_restore -h new-superset-postgresql -p 5432 -U superset -d your_new_database_name /tmp/superset_backup.dump ``` - **Run Superset Migrations**: After restoring the database, run the following commands to upgrade the Superset metadata: ```bash superset db upgrade superset init ``` Ensure that you have the necessary permissions and that your environment variables are correctly set for the database connections. If you encounter specific errors during `pg_restore`, they might need to be addressed individually based on the error messages. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
