Special thanks to Hannes Ljungberg for finding multiple implementation
gaps.
Thanks also to Simon Charette, Adam Johnson, and Mariusz Felisiak for
reviews.
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.
Refs #32369, #30408, #30593.
This ensures that constraint violations are tested in isolation from
each other as an IntegrityError only ensures a least one constraint is
violated.
For example, the assertion added in 42e8cf4 break both the
name_constraint_rhs and the rebate_constraint constraints and thus
doesn't constitute a proper regression test. Refs #32369.
The new logic mirrors the logic in SchemaEditor._delete_check_sql()
added in 68ef274bc505cd44f305c03cbf84cf08826200a8.
Thanks Tim Graham for the report.
Thanks Jared Chung, Tom Carrick, David Smith, Nick Pope, and Mariusz

This prevents duplicated operations when altering type of primary key
with MTI and foreign key. Previously, a foreign key to the base model
was added twice, once directly and once by the inheritance model.
Thanks bcail for the report.
Regression in 325d7710ce9f6155bb55610ad6b4580d31263557.
This adjusts Expressions.rename_table_references() to only update alias
when needed.

This disables interpolation of constraint creation statements. Since
Constraint.create_sql interpolates its parameters instead of deferring
this responsibility to the backend connection it must disable
connection level parameters interpolation.
