2015-06-30Fixed #23658 -- Provided the password to PostgreSQL dbshell commandJean-Michel Vourgère
The password from settings.py is written in a temporary .pgpass file file whose name is given to psql using the PGPASSFILE environment variable.
2015-06-22Fixed #25002 -- Used PostgreSQL column type alteration USING clause.Simon Charette
Thanks to Dirk Uys for the report.
2015-06-19Fixed #23804 -- Added RasterField for PostGIS.Daniel Wiesmann
Thanks to Tim Graham and Claude Paroz for the reviews and patches.
2015-06-05Fixed #24767 -- Added Greatest and Least expressionsIan Foote
Greatest and Least are row-level Function versions of Min and Max.
2015-06-02Fixed #24892 -- Fixed quoting of SQL when renaming a field to AutoField in ↵Tim Graham
PostgreSQL
2015-06-02Fixed #9596 -- Added date transform for DateTimeField.Jon Dufresne
2015-05-24Well, what should I say: UPS.Florian Apolloner
2015-05-24Fixed #24844 -- Corrected has_changed implementation for HStoreField.Andrea Grandi
2015-05-17Dropped the needs_datetime_string_cast feature.Aymeric Augustin
It has been superseded by the converter infrastructure.
2015-05-17Fixed #23820 -- Supported per-database time zone.Aymeric Augustin
The primary use case is to interact with a third-party database (not primarily managed by Django) that doesn't support time zones and where datetimes are stored in local time when USE_TZ is True. Configuring a PostgreSQL database with the TIME_ZONE option while USE_TZ is False used to result in silent data corruption. Now this is an error.
2015-05-17Renamed value_to_db_xxx to adapt_xxxfield_value.Aymeric Augustin
This mirrors convert_xxxfield_value nicely, taking advantage of the adapter/converter terminology which is commonly used by DB-API modules.
2015-05-15Fixed #24791 -- Added fallback when 'postgres' database isn't availableClaude Paroz
Thanks Carl Meyer and Tim Graham for the reviews.
2015-04-17Fixed #24595 -- Prevented loss of null info in MySQL field alterationClaude Paroz
Thanks Simon Percivall for the report, and Simon Charette and Tim Graham for the reviews.
2015-03-29Fixed #19259 -- Added group by selected primary keys support.Simon Charette
2015-03-25Renamed Field.rel attribute to remote_fieldAnssi Kääriäinen
Field.rel is now deprecated. Rel objects have now also remote_field attribute. This means that self == self.remote_field.remote_field. In addition, made the Rel objects a bit more like Field objects. Still, marked ManyToManyFields as null=True.
2015-02-16Fixed #24335 -- Bumped required psycopg2 version to 2.4.5 (2.5 for ↵Tim Graham

2015-01-17Required sqlparse for SQL splitting per deprecation timeline.Tim Graham
2015-01-16Fixed #24092 -- Widened base field support for ArrayField.Marc Tamlyn
Several issues resolved here, following from a report that a base_field of GenericIpAddressField was failing. We were using get_prep_value instead of get_db_prep_value in ArrayField which was bypassing any extra modifications to the value being made in the base field's get_db_prep_value. Changing this broke datetime support, so the postgres backend has gained the relevant operation methods to send dates/times/datetimes directly to the db backend instead of casting them to strings. Similarly, a new database feature has been added allowing the uuid to be passed directly to the backend, as we do with timedeltas. On the other side, psycopg2 expects an Inet() instance for IP address fields, so we add a value_to_db_ipaddress method to wrap the strings on postgres. We also have to manually add a database adapter to psycopg2, as we do not wish to use the built in adapter which would turn everything into Inet() instances. Thanks to smclenithan for the report.

refs #22340.
2014-12-30Removed db.backends methods which only call super().Tim Graham
2014-12-23Fixed #24033 -- Use interval type on Oracle.Marc Tamlyn
Use INTERVAL DAY(9) TO SECOND(6) for Durationfield on Oracle rather than storing as a NUMBER(19) of microseconds. There are issues with cx_Oracle which require some extra data manipulation in the database backend when constructing queries, but it handles the conversion back to timedelta objects cleanly. Thanks to Shai for the review.
2014-12-20Fixed #2443 -- Added DurationField.Marc Tamlyn
A field for storing periods of time - modeled in Python by timedelta. It is stored in the native interval data type on PostgreSQL and as a bigint of microseconds on other backends. Also includes significant changes to the internals of time related maths in expressions, including the removal of DateModifierNode. Thanks to Tim and Josh in particular for reviews.
