Upgarding supabase postgres to 15.7 ?

Hello,
Supabase is great, but the latest version of postgresql 15, is 15.7.
And currently if we run supabase/postgres service in docker, we can see it is based on Postgres 15.1.x
Is there a roadmap to upgrade current supabase/docker image to supabase/postgres: 15.7 ?
Ideally, in 6 months or one year maybe ?
Or is there a way to contribute in some ways by generating and testing a new supabase/postgres: 15.7 image.
Thanks & take care,
Thomas
