descriptions on how I tried to reproduce it.

   1. As seen in the above image, started with airflow version 2.9.2. MySQL 
backend version 8.0.40. 
   2. Ran a sample DAG multiple times to populate some metadata.
   3. Executed `airflow db downgrade --to-version=2.8.2 --yes`
   Revision id applied is 88344c1d9134 and downgrade completed successfully.
   4. Upgraded successfully using `airflow db migrate` 
   
   After the upgrade and downgrade, I checked a few things in the database (see 
image below):
   The unique key on the connection table is named connection_conn_id_uq. When 
I ran the query that caused the error mentioned in this issue, it executed 
without any errors.The query output is also shown in the image.
