- apply autopep8 + manual fixes to most of test/sql/
as a scalar subquery such as within an IN would receive inappropriate substitutions from the enclosing query, if the same table were present inside the subquery as were in the enclosing query such as in a joined inheritance scenario. fixes #3130
to again have the chance to veto rendering, as the naming convention can make the decision that the name is "none" or not now.
constraint convention that includes ``constraint_name`` would then force all :class:`.Boolean` and :class:`.Enum` types to require names as well, as these implicitly create a constraint, even if the ultimate target backend were one that does not require generation of the constraint such as Postgresql. The mechanics of naming conventions for these particular constraints has been reorganized such that the naming determination is done at DDL compile time, rather than at constraint/table construction time. fixes #3067
for the ``description_encoding`` dialect parameter, which when not explicitly set was preventing cursor.description from being parsed correctly in the case of result sets that contained names in alternate encodings. This parameter shouldn't be needed going forward. fixes #3091
parameters could be expressed in the wrong final order when CTEs were nested in certain ways. fixes #3090
to check subsequent values entries beyond the first one given for literal SQL expressions. fixes #3069
Python version < 2.6.5, working around the "no unicode keyword arg" bug as these args are passed along as keyword args within some reflection processes. fixes #3123
