I can see the use case too (specially for monitoring tools) of being

What do you think about adding a function in core PG to provide such 
functionality? (means being able to retrieve all the stats (+ eventually 
add some filtering) without the need to connect to each database).

If there is some interest, I'd be happy to work on it and propose a patch.
