        .. versionadded:: 1.4 - the :meth:`.Inspector.has_table` method
           replaces the :meth:`_engine.Engine.has_table` method.

        .. versionchanged:: 2.0:: :meth:`.Inspector.has_table` now formally
           supports checking for additional table-like objects:

           * any type of views (plain or materialized)
           * temporary tables of any kind

           Previously, these two checks were not formally specified and
           different dialects would vary in their behavior.   The dialect
           testing suite now includes tests for all of these object types
           and should be supported by all SQLAlchemy-included dialects.
           Support among third party dialects may be lagging, however.
