postgres: Disabling foreign key constraints outside of transaction throws warning #19474

Description

Setting constraints is only valid inside a transaction which configures when the key constraints are applied - immediate or deferred.

When we disable/enable constraints, postgres throws a WARNING:

WARNING:  SET CONSTRAINTS can only be used in transaction blocks

It seems cake has a feature enum that would cover this that's set to false for postgres:

 DriverFeatureEnum::DISABLE_CONSTRAINT_WITHOUT_TRANSACTION => false,
