Yes, this tutorial helped me successfully upgrade PostgreSQL. Thank you very much. However, now there is another issue, which is that the volume name for the asset has also changed: 1.15.2: penpot_assets_data. 1.17.2: penpot_assets.
If I directly copy the penpot_assets_data volume to penpot_assets, there will still be errors. After testing, I found that I need to copy penpot_assets_data/assets to penpot_assets, and then it will work. However, I do not know if there will be any other issues with this operation, and I have not found any relevant documentation. I want to confirm if what I did is appropriate.
