Feature description

3.0.0RC5 generated model for pgsql using generic uuid type uuid.UUID, which need to be manually converted to the UUID type from sqlalchemy.dialects.postgresql:
from sqlalchemy.dialects.postgresql import UUID

from:
uuid: Mapped[uuid.UUID] = mapped_column(Uuid, primary_key=True)
to:
uuid: Mapped[UUID] = mapped_column(Uuid, primary_key=True)

Use case

You'll need this every time you generate the models from pgsql which contains uuid type.

Pushed a possible fix. A bit hacky but give it a look. Tested locally on my database and works, wanted to run the repo tests and potentially add a test for this case, but they seem to be failing on master
