Astro Dev Start Failure- Postgres database files are incompatible with server

When I run astro dev start the airflow server fails to start. The Postgres container fails to start with the following error:

PostgreSQL Database directory appears to contain a database; Skipping initialization

2021-08-18 17:01:49.091 UTC [1] FATAL:  database files are incompatible with server
2021-08-18 17:01:49.091 UTC [1] DETAIL:  The data directory was initialized by PostgreSQL version 10, which is not compatible with this version 12.2 (Debian 12.2-2.pgdg100+1).

Does anybody have any suggestions?

Thanks you,

Have you used astro dev previously on this machine? Try running astro dev kill to close out any existing database and restarting then with astro dev start
