Only if you have self-referencing FKs in partitioned tables. It
would be an interesting data point to verify whether this reports

the case I'm suspicious about: a multi-level hierarchy containing an FK
that points to an intermediate level of itself.

wants to chat sometime or whatever is welcome to ping me.
