Closes #2934

Have also considered linking column.label() to the "column" itself being
in the result map but this reveals some naming collision problems (that
also seem to be very poorly tested...). This should be as far as
we want to go right now with [ticket:2932].

using a column key of the form ``<tablename>_<columnname>``
matching that of an aliased column in the text would still not
match at the ORM level, which is ultimately due to a core
column-matching issue. Additional rules have been added so that the
column ``_label`` is taken into account when working with a
:class:`.TextAsFrom` construct or with literal columns.

pymysql) from working in Py3K, where a check for "connection
charset" would fail due to Py3K's more strict value comparison
rules. The call in question wasn't taking the database
version into account in any case as the server version was
still None at that point, so the method overall has been
simplified to rely upon connection.character_set_name().

to support dialect-level reflection options for all :class:`.Table`
objects reflected.
- Added a new dialect-level argument ``postgresql_ignore_search_path``;
this argument is accepted by both the :class:`.Table` constructor
as well as by the :meth:`.MetaData.reflect` method. When in use
against Postgresql, a foreign-key referenced table which specifies
a remote schema name will retain that schema name even if the name
is present in the ``search_path``; the default behavior since 0.7.3
has been that schemas present in ``search_path`` would not be copied
to reflected :class:`.ForeignKey` objects. The documentation has been
updated to describe in detail the behavior of the ``pg_get_constraintdef()``
function and how the ``postgresql_ignore_search_path`` feature essentially
determines if we will honor the schema qualification reported by
this function or not. [ticket:2922]

the schema target of a :class:`.ForeignKey` will not be changed unless
that schema matches that of the parent table. That is, if
a table "schema_a.user" has a foreign key to "schema_b.order.id",
the "schema_b" target will be maintained whether or not the
"schema" argument is passed to :meth:`.Table.tometadata`. However
if a table "schema_a.user" refers to "schema_a.order.id", the presence
of "schema_a" will be updated on both the parent and referred tables.
This is a behavioral change hence isn't likely to be backported to
0.8; it is assumed that the previous behavior is pretty buggy
however and that it's unlikely anyone was relying upon it.
Additionally, a new parameter has been added
:paramref:`.Table.tometadata.referred_schema_fn`. This refers to a
callable function which will be used to determine the new referred
schema for any :class:`.ForeignKeyConstraint` encountered in the
tometadata operation. This callable can be used to revert to the
previous behavior or to customize how referred schemas are treated
on a per-constraint basis. [ticket:2913]

oriented row lookups were not matching up to the ad-hoc :class:`.ColumnClause`
objects that :class:`.TextAsFrom` generates, thereby making it not
usable as a target in :meth:`.Query.from_statement`. Also fixed
:meth:`.Query.from_statement` mechanics to not mistake a :class:`.TextAsFrom`
for a :class:`.Select` construct. This bug is also an 0.9 regression
as the :meth:`.Text.columns` method is called to accommodate the
:paramref:`.text.typemap` argument. [ticket:2932]

applied to :class:`.Constraint` and :class:`.Index` objects. Based
on a recipe in the wiki, the new feature uses schema-events to set up
names as various schema objects are associated with each other. The
events then expose a configuration system through a new argument
:paramref:`.MetaData.naming_convention`. This system allows production
of both simple and custom naming schemes for constraints and indexes
on a per-:class:`.MetaData` basis. [ticket:2923]

to disable autoflush, in the case that the attribute needs to lazy-load

kinds of many-to-one. A flush at this point otherwise occurs
at the point that the attribute is None and can cause NULL violations.

- Fixed bug whereby binary type would fail in some cases
if used with a "test" dialect, such as a DefaultDialect or other
dialect with no DBAPI.
- Fixed bug where "literal binds" wouldn't work with a bound parameter
that's a binary type. A similar, but different, issue is fixed
in 0.8.

would lead to ``TypeError`` when compared to non-tuple types as it attempted
to apply tuple() to the "other" object unconditionally. The
full range of Python comparison operators have now been implemented on
:class:`.RowProxy`, using an approach that guarantees a comparison
system that is equivalent to that of a tuple, and the "other" object
is only coerced if it's an instance of RowProxy. [ticket:2924]

:class:`.Query` and in other situations where selects or joins
were aliased (such as joined table inheritance) could fail if a
user-defined :class:`.Column` subclass were used in the expression.
In this case, the subclass would fail to propagate ORM-specific
"annotations" along needed by the adaptation. The "expression
annotations" system has been corrected to account for this case.
