- Postgres: Do not prefix table with schema in: "FOR UPDATE of "

2015-11-24T18:58:50+00:00

For example, this query:

    SELECT s1.users.name FROM s1.users FOR UPDATE OF s1.users

should actually be:

    SELECT s1.users.name FROM s1.users FOR UPDATE OF users

fixes #3573

fix postgresql exclude contraint to check when= against None rather than bool eval

2015-11-23T18:22:50+00:00

- Fixed the ``.python_type`` attribute of :class:`.postgresql.INTERVAL`

2015-11-19T20:11:37+00:00

to return ``datetime.timedelta`` in the same way as that of
:obj:`.types.Interval.python_type`, rather than raising
``NotImplementedError``.
fixes #3571

(cherry picked from commit 29d6f6e19b014bb5ce79032bd8803e32b4da0e5e)

- Added support for reflecting the source of materialized views

2015-11-18T14:06:33+00:00

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

Updated PostgreSQL links to point to "current" rather than hardcoded version

2015-11-05T23:34:27+00:00

Update links in SQLAlchemy docs that point to postgres docs to use 'devel' rather than hardcoded version

2015-11-04T19:59:28+00:00

- Added a new type-level modifier :meth:`.TypeEngine.evaluates_none`

2015-09-19T20:27:51+00:00

which indicates to the ORM that a positive set of None should be
persisted as the value NULL, instead of omitting the column from
the INSERT statement.  This feature is used both as part of the
implementation for :ticket:`3514` as well as a standalone feature
available on any type.  fixes #3250
- add new documentation section illustrating the "how to force null"
 use case of #3250
- alter our change from #3514 so that the class-level flag is now
called "should_evaluate_none"; so that "evaluates_none" is now
a generative method.

- The use of a :class:`.postgresql.ARRAY` object that refers

2015-09-19T15:58:50+00:00

to a :class:`.types.Enum` or :class:`.postgresql.ENUM` subtype
will now emit the expected "CREATE TYPE" and "DROP TYPE" DDL when
the type is used within a "CREATE TABLE" or "DROP TABLE".
fixes #2729

- add a postgresql-specific form of array_agg() that injects the

2015-08-27T15:22:05+00:00

ARRAY type, references #3132
