There is one implementation of hints available as an extension: https://github.com/ossc-db/pg_hint_plan

It's unfortunate that it comes off as if maintainers think planner is good enough, because that is demonstrably not true. And from my discussions there is wide agreement that the planner will never be perfect. But agreeing that it's something that needs work is not enough, someone actually has to do the work too. Reality is that implementing any feature to PostgreSQL quality standards is hard work.
