for types where you need to fully specify DDL from the ground up you use UserDefinedType:
http://docs.sqlalchemy.org/en/rel_0_9/core/types.html?highlight=userdefinedtype#sqlalchemy.types.UserDefinedType if this type is more in the realm of having to emit PG’s “CREATE TYPE” and all that, that’s more intricate, you’d need to look into also subclassing SchemaType simultaneously, which is a little less end-user friendly, let me know if you need that/need help with that.
