Tom Lane	2ec993a7cb	Support triggers on views. ... This patch adds the SQL-standard concept of an INSTEAD OF trigger, which is fired instead of performing a physical insert/update/delete. The trigger function is passed the entire old and/or new rows of the view, and must figure out what to do to the underlying tables to implement the update. So this feature can be used to implement updatable views using trigger programming style rather than rule hacking. In passing, this patch corrects the names of some columns in the information_schema.triggers view. It seems the SQL committee renamed them somewhere between SQL:99 and SQL:2003. Dean Rasheed, reviewed by Bernd Helmle; some additional hacking by me.	15 years ago
Peter Eisentraut	dd4cd55c15	Python 3 support in PL/Python ... Behaves more or less unchanged compared to Python 2, but the new language variant is called plpython3u. Documentation describing the naming scheme is included.	16 years ago
Peter Eisentraut	2e3b16c8ba	Improve PL/Python elog output ... When the elog functions (plpy.info etc.) get a single argument, just print that argument instead of printing the single-member tuple like ('foo',).	16 years ago
Peter Eisentraut	4ab6ebf3f4	Add Unicode support in PL/Python ... PL/Python now accepts Unicode objects where it previously only accepted string objects (for example, as return value). Unicode objects are converted to the PostgreSQL server encoding as necessary. This change is also necessary for future Python 3 support, which treats all strings as Unicode objects. Since this removes the error conditions that the plpython_unicode test file tested for, the alternative result files are no longer necessary.	17 years ago
Peter Eisentraut	27c405d61a	Enhanced error context support in PL/Python ... Extract the "while creating return value" and "while modifying trigger row" parts of some error messages into another layer of error context. This will simplify the upcoming patch to improve data type support, but it can stand on its own.	17 years ago
Peter Eisentraut	5dff93638c	Make PL/Python tests more compatible with Python 3 ... This changes a bunch of incidentially used constructs in the PL/Python regression tests to equivalent constructs in cases where Python 3 no longer supports the old syntax. Support for older Python versions is unchanged.	17 years ago
Peter Eisentraut	cfe380a6dd	Augment test coverage in PL/Python, especially for error conditions.	17 years ago
Peter Eisentraut	9d9848668f	Split the plpython regression test into test cases arranged by topic, instead ... of the previous monolithic setup-create-run sequence, that was apparently inherited from a previous test infrastructure, but makes working with the tests and adding new ones weird.	17 years ago
