Opened up two tests that now pass with pg8000. Also, rewrote two tests
to use actual tables rather than having a round trip in a single select
statement. This is necessary for pg8000 because it sends strings to the
server with type 'unknown' and lets the server work out the type.

mapper is implicitly combining one of its column-based attributes
with that of the parent, where those columns normally don't necessarily
share the same value. This is an extension of an existing check that
was added via :ticket:`1892`; however this new check emits only a
warning, instead of an exception, to allow for applications that may
be relying upon the existing behavior.

when that :class:`.Column` is referred to in an explicit
:class:`.PrimaryKeyConstraint` for that table. This behavior now
matches that of when the :class:`.Column` itself has the
:paramref:`.Column.primary_key` flag set to ``True``, which is
intended to be an exactly equivalent case.

While "oid" is generally a private type within PG that is not exposed
in modern versions, there are some PG use cases such as large object
support where these types might be exposed, as well as within some
user-reported schema reflection use cases.

on an index needed to have the same quoting for quoted names in
order to be recognized. The fix makes the quotes optional but
also provides the old behavior for backwards compatibility with those
using the workaround.

columns are always added to the list of columns to be "undeferred";
otherwise, the ORM can't load the row's identity. Apparently,
one can defer the mapped primary keys and the ORM will fail, that
hasn't been changed. But as load_only is essentially saying
"defer all but X", it's more critical that PK cols not be part of this
deferral. fixes #3080

event.listen and event.listen_for have a kwarg once added in 0.9.4 (not 0.9.3) CHANGELOG agrees with this as well. (as does my manual testing)

- Fixed bug which would occur if a DBAPI exception
occurs when the engine first connects and does its initial checks,
and the exception is not a disconnect exception, yet the cursor
raises an error when we try to close it. In this case the real
exception would be quashed as we tried to log the cursor close
exception via the connection pool and failed, as we were trying
to access the pool's logger in a way that is inappropriate
in this very specific scenario. fixes #3063

mixin or abstract class when accessed, so that modifications made
to this dictionary by declarative itself won't conflict with that
of other mappings. The dictionary is modified regarding the
``version_id_col`` and ``polymorphic_on`` arguments, replacing the
column within with the one that is officially mapped to the local
class/table. fixes #3062

As with postgresql+psycopg2,
execution_options(isolation_level='AUTOCOMMIT') now works for the
postgresql+pg8000 dialect.

pg8000 uses binary transfer of floats and so accuracy is lost for floats
that can't be represented exactly in binary.

The two tests, test_create_table() and test_unicode_labels() previously
failed under pg8000, but now they pass, so this commit opens them up.

We can now update the requirements to remove the special case of pg8000
truncating decimals.

if an exception is a "disconnect" error; ideally, this should remove
the need for any other inspection of the exception message to detect
disconnect, however we will leave those existing messages in place
as a fallback. This should be able to handle newer cases like
"SSL EOF" conditions. Pull request courtesy Dirk Mueller.

If there is a closed attribute on the connection and
it is true, return true. Implements a todo in the code
and helps in one specific disconnect case where it previously
did not match because the error message was "unknown error".

of work such that loading for related many-to-one objects is slightly
more aggressive, in the case of a graph of self-referential objects
that are to be deleted; the load of related objects is to help
determine the correct order for deletion if passive_deletes is
not set.
- revert the changes to test_delete_unloaded_m2o, these deletes do in fact
need to occur in the order of the two child objects first.

that might take one of multiple directions; apply this to test_delete_unloaded_m2o
which is now illustrating multiple paths due to #3060/#3061, though still doing the
right thing.
