    The pypostgresql dialect is **not tested as part of SQLAlchemy's continuous
    integration** and may have unresolved issues.  The recommended PostgreSQL
    driver is psycopg2.

   in a future version. This DBAPI is superseded by the external
    version available at external-dialect_. Please use the external version or
    one of the supported DBAPIs to connect to PostgreSQL.
