Validating an unvalidated foreign key that references a partitioned table would try to queue validations for each individual partition of the referenced table, but this is wrong: each individual partition would not necessarily have all the referenced rows, so errors would be raised. Avoid doing that. The pg_constraint rows that cause this to happen are only there to support the action triggers that implement the DELETE/ UPDATE actions of the FK, so no validating scan is necessary. This was an oversight in commit b663b9436e75. An equivalent oversight exists for NOT ENFORCED constraints, which is not fixed in this commit.
