### Search before asking - [x] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened Hi! As a new user, I was setting up the standalone server (version 3.3.1) using the official Docker image. When I tried to add a PostgreSQL datasource, I received an "Illegal Datasource" warning, and I was unable to proceed. As a new user, this was confusing because I expected the standalone image to support common databases like PostgreSQL out of the box. <img width="2048" height="1206" alt="Image" src="https://github.com/user-attachments/assets/81d8a8d1-b981-4260-8595-8a3380fe5576"; /> After some troubleshooting, I discovered that the required datasource plugin (.jar file) is not included in the Docker image by default. I tried to install standalone lower version (3.2.1) and it can connect to my db. ### What you expected to happen I expect everything worked perfectly. The same applies to version 3.2.1. ### How to reproduce You can run the official standalone Docker image for version 3.3.1:, then access the UI and log in. Go to the DataSource Center and try to create a new POSTGRESQL datasource. The UI will show an "Illegal Datasource" warning. ### Anything else This is more of a user experience suggestion than a bug report. Thank you for this great project! BTW ### Version 3.3.1 ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
