Correction de bogues

• La compatibilité pour psycopg2 2.8 a été ajoutée (#30331).

• Correction d’une régression dans Django 2.2 qui provoquait un plantage au chargement du gabarit pour le page de débogage technique 500 (#30324).

• Correction d’un plantage du paramètre ordering dans ArrayAgg et StringAgg lorsqu’il contient une expression avec paramètres (#30332).

• Correction d’une régression dans Django 2.2 qui faisait que la suppression rapide d’une instance unique ne définissait plus la clé primaire à None (#30330).

• Prevented makemigrations from generating infinite migrations for check constraints and partial indexes when condition contains a range object (#30350).

• Reverted an optimization in Django 2.2 (#29725) that caused the inconsistent behavior of count() and exists() on a reverse many-to-many relationship with a custom manager (#30325).

• Fixed a regression in Django 2.2 where Paginator crashes if object_list is a queryset ordered or aggregated over a nested JSONField key transform (#30335).

• Fixed a regression in Django 2.2 where IntegerField validation of database limits crashes if limit_value attribute in a custom validator is callable (#30328).

• Fixed a regression in Django 2.2 where SearchVector generates SQL that is not indexable (#30385).

• Fixed a regression in Django 2.2 that caused an exception to be raised when a custom error handler could not be imported (#30318).

• Fixed a migration crash on Oracle and SQLite when adding a check constraint with condition contains | (OR) operator (#30412).
