frames.

mlr3db 0.1.5
as_data_backend() method to construct a
DataBackendDplyr now specialized to operate on objects of
type "tbl_lazy" (was "tbl" before). This way,
local "tbl" objects such as tibbles are converted to a
DataBackendDataTable by
mlr3::as_data_backend.data.frame().
mlr3db 0.1.4

user-provided function.
DataBackendDplyr now has a finalizer which
automatically disconnects the database connection during garbage
collection.
