defineComposites :: MonadDB m => [CompositeType] -> m () Source #

Composite types are static in a sense that they can either be created or dropped, altering them is not possible. Therefore they are not part of the migration process. This is not a problem since their exclusive usage is for intermediate representation of complex nested data structures fetched from the database.
