Someone managed to run Linux on a Pixel 9 Pro XL (Android phone from Google) using the Terminal app, setting up XFCE within it. https://old.reddit.com/r/GooglePixel/comments/1ja82u9/working_linux_xfce_on_pixel_9_pro_xl/

There's even a wiki explaining how to do it.
But I really love to have PostgreSQL running on Android.
With psql you can access any PostgreSQL instance in your reach, not only the local instance.
