Postgresql table reflection will ensure that the
:paramref:`.Column.autoincrement` flag is set to False when reflecting
a primary key column that is not of an :class:`.Integer` datatype,
even if the default is related to an integer-generating sequence.
This can happen if a column is created as SERIAL and the datatype
is changed.  The autoincrement flag can only be True if the datatype
is of integer affinity in the 1.1 series.

This bug is related to a test failure in downstream sqlalchemy_migrate.

Previously, it was impossible to have a Table that has
None for a schema name when the "schema" parameter on
MetaData was set.  A new symbol sqlalchemy.schema.BLANK_SCHEMA
is added which indicates that the schema name should unconditionally
be set to None.  In particular, this value must be passed within
cross-schema foreign key reflection, so that a Table which
is in the "default" schema can be represented properly.

- modernize those tests as well

to the Postgresql version of the :meth:`.Inspector.get_view_definition`
method.
fixes #3587

options and USING of :ticket:`3455` released in 1.0.6,
to disable the feature for Postgresql versions < 8.2 where the
``reloptions`` column is not provided; this allows Amazon Redshift
to again work as it is based on an 8.0.x version of Postgresql.
