I would have expected an empty result too.  Can you confirm that
p_ci_pipelines used to be a partition of something?  Can you show us
the full DDL (or psql \d+ output) for the partitioned table it
used to be part of, and for that matter also for p_ci_pipelines?
Did the FK used to reference the whole partitioned table, or just
this partition?

I'm suspicious that our repair recipe might not have accounted
for self-reference FKs fully, but that's just a gut feeling at
this point.
