It would be nice if there could be an example that shows how to direct the code execution to certain routines after wake-up from a low power state i.e. not to start at main(). This should be possible using POWMAN boot vector described in section 5.2.3 in the datasheet.

powman is a different API. There are some simple examples here https://github.com/peterharperuk/pico-examples/tree/powman Restarting into a ram function is doable but then what? Your hardware was switched off so it all needs to be reset. So you're limited in what you can do and you may as well just run main.

I'm going to merge this...
