PostgREST and postgres-meta have endpoint for health-check. But these containers don't have curl or wget.

• PostgREST: http://localhost:3001/live
• postgres-meta: http://localhost:8080/health

Health check is apparently a must for realtime to work at all https://github.com/supabase/supabase/issues/25841
