After upgrading psycopg to v3 I think you will need to change any postgres connection urls to postgresql+psycopg:// to target the psycopg3 driver.. See https://docs.sqlalchemy.org/en/20/dialects/postgresql.html#module-sqlalchemy.dialects.postgresql.psycopg

Not sure this is going to work with the existing postgres connection urls, if I'm reading the documentation right,

Looks good now.
