Deprecated functions from pytest-posgresql?

I'm looking at the [configuration example](https://github.com/jeancochrane/pytest-flask-sqlalchemy#configuration), which seems to be an extract from [_confest.py](https://github.com/jeancochrane/pytest-flask-sqlalchemy/blob/master/tests/_conftest.py#L25-L61). In _conftest.py you `from pytest_postgresql.factories import (init_postgresql_database, drop_postgresql_database)`. I'm not sure if I'm supposed to `pip install pytest-postgresql` myself but, in any case, I'm wondering about `init_postgresql_database` and `drop_postgresql_database`. These 2 functions are apparently deprecated in [pytest-postgresql 2.1.0](https://pypi.org/project/pytest-postgresql/), released on September 10, 2019. Does the configuration example need updating or am I just off track here?

Thanks

Start with the configuration example and tests/_conftest.py at lines 25-61, then compare the imported functions with the pytest-postgresql 2.1.0 documentation. Verify whether the example and fixture setup still use supported APIs, and consider the work complete when the documented configuration is current and the related tests pass.
