Reproduction steps

1. Open any Rails project with PostgreSQL database.
2. Run the command bin/rails db:drop in the terminal.
3. Observe the error message stating that the database cannot be dropped because it is being accessed by another user.

This is expected because the Rails add-on would still have its Rails process active. I'm not sure how we could solve this, as we would to intercept that command and trigger the LSP to shutdown.

To workaround this for now, you should be able to stop Ruby LSP (Commmand-Shift-P then 'RubyLSP: Stop') before running db:drop.
