That's a problem. I really think that we should make the steps of the
concurrent operation consistent across all relations, meaning that all
the indexes should be created as invalid for all the parts of the
partition tree, including partitioned tables as well as their
partitions, in the same transaction. Then a second new transaction
gets used for the index build, followed by a third one for the
validation that switches the indexes to become valid.
