Simon Charette ffff17d4b0 Fixed #34553 -- Fixed improper % escaping of literal in constraints.
Proper escaping of % in string literals used when defining constaints
was attempted (a8b3f96f6) by overriding quote_value of Postgres and
Oracle schema editor. The same approach was used when adding support for
constraints to the MySQL/MariaDB backend (1fc2c70).

Later on it was discovered that this approach was not appropriate and
that a preferable one was to pass params=None when executing the
constraint creation DDL to avoid any form of interpolation in the first
place (42e8cf47).

When the second patch was applied the corrective of the first were not
removed which caused % literals to be unnecessary doubled. This flew
under the radar because the existings test were crafted in a way that
consecutive %% didn't catch regressions.

This commit introduces an extra test for __exact lookups which
highlights more adequately % doubling problems but also adjust a
previous __endswith test to cover % doubling problems (%\% -> %%\%%).

Thanks Thomas Kolar for the report.

======
Django
======

Django is a high-level Python web framework that encourages rapid development
and clean, pragmatic design. Thanks for checking it out.

All documentation is in the "``docs``" directory and online at
https://docs.djangoproject.com/en/stable/. If you're just getting started,
here's how we recommend you read the docs:

* First, read ``docs/intro/install.txt`` for instructions on installing Django.

* Next, work through the tutorials in order (``docs/intro/tutorial01.txt``,
  ``docs/intro/tutorial02.txt``, etc.).

* If you want to set up an actual deployment server, read
  ``docs/howto/deployment/index.txt`` for instructions.

* You'll probably want to read through the topical guides (in ``docs/topics``)
  next; from there you can jump to the HOWTOs (in ``docs/howto``) for specific
  problems, and check out the reference (``docs/ref``) for gory details.

* See ``docs/README`` for instructions on building an HTML version of the docs.

Docs are updated rigorously. If you find any problems in the docs, or think
they should be clarified in any way, please take 30 seconds to fill out a
ticket here: https://code.djangoproject.com/newticket

To get more help:

* Join the ``#django`` channel on ``irc.libera.chat``. Lots of helpful people
  hang out there. See https://web.libera.chat if you're new to IRC.

* Join the django-users mailing list, or read the archives, at
  https://groups.google.com/group/django-users.

To contribute to Django:

* Check out https://docs.djangoproject.com/en/dev/internals/contributing/ for
  information about getting involved.

To run Django's test suite:

* Follow the instructions in the "Unit tests" section of
  ``docs/internals/contributing/writing-code/unit-tests.txt``, published online at
  https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/unit-tests/#running-the-unit-tests
