@tyt2y3 Status?

@tyt2y3 Is there anything I can do to get this merged?

Thank you! but sorry I don't think we should piggy back on Type::Unknown. Actually I think we can add a new variant to postgres/def/types.rs and use it!

Note: https://github.com/SeaQL/sea-schema/blob/master/src/postgres/def/types.rs#L146, https://github.com/SeaQL/sea-schema/blob/master/src/postgres/def/types.rs#L211

@billy1624 Hello, seems like this might be in need of a bump.
