[I] Make sure the Celery result backend works with psycopg3 upgrade [airflow]
jason810496 opened a new issue, #74732:
URL: https://github.com/apache/airflow/issues/74732
### Body
> [74581](https://github.com/apache/airflow/pull/74581) prepare_threshold=None applies to Airflow's metadata engines only. The commit message names the Celery result backend as out of scope and states a bare postgresql:// resolves to psycopg on SQLAlchemy 2.1. 3.4.0b1 constraints pin SQLAlchemy 2.1.4.
- We _might_ need to follow the pattern in https://github.com/apache/airflow/pull/74581 for Celery SQLAlchemy engine option.
- Or it's fine to keep it as-is (since it really depends on the Celery implementation itself at the statement level)
### Committer
- [x] I acknowledge that I am a maintainer/committer of the Apache Airflow project.

Hi @jason810496, I'd be interested in investigating #74732. I can test the Celery result backend with psycopg3 and PostgreSQL behind transaction-mode PgBouncer, then report whether prepared statements cause failures. If reproducible, I could add a focused regression test and fix. Would that approach be useful?
