Mypy errors when generating migration

[4c0n]

Generating the migration goes well and executing works like a charm, however mypy has a few complaints:

migrations/versions/cd7033b17112_update_form_component_types_enum.py:13: error: Module "alembic_postgresql_enum" does not explicitly export attribute "TableReference"  [attr-defined]
migrations/versions/cd7033b17112_update_form_component_types_enum.py:26: error: Module has no attribute "sync_enum_values"  [attr-defined]
migrations/versions/cd7033b17112_update_form_component_types_enum.py:44: error: Module has no attribute "sync_enum_values"  [attr-defined]

I'm running mypy in strict mode btw. I suppose the first one could be fixed easily by either defining __all__ in the __init__.py or by using:

from .get_enum_data import ColumnType as ColumnType
from .get_enum_data import TableReference as TableReference

instead of:

from .get_enum_data import ColumnType, TableReference

Not sure how to go about fixing the others though.
