It would be awesome if this were to make it in core. Jelte did a bunch of work to improve query protocol changes. Having Postgres accept Otel trace propagation would be a gamechanger for debugging the clients and DB together. Especially since ~80%+ of DB related issues I see come down to some sort of long running open transaction which Postgres knows nothing about server-side.
It looks abandoned.
Or complete?
Unlikely, as it states:

PostgresSQL is already at 18.
