That's true.
For example, in the case of PostgreSQL, there is already a tool called pg_isready [0] to do this inside a healthcheck as you described.
services:
postgres-db:
image: postgres
healthcheck:
test: ["CMD-SHELL", "pg_isready -U postgres"]
application:
image: image
depends_on:
postgres-db:
condition: service_healthy
However, this is not the case for other databases/services.
