The fix for concurrent index operations in bc32a12e0db2 started considering indexes that are not yet marked indisvalid as arbiters for INSERT ON CONFLICT. For partitioned tables, this leads to including indexes that may not exist in partitions, causing a trivially reproducible "invalid arbiter index list" error to be thrown because of failure to match the index. To fix, it suffices to ignore !indisvalid indexes on partitioned tables. There should be no risk that the set of indexes will change for concurrent transactions, because in order for such an index to be marked valid, an ALTER INDEX ATTACH PARTITION must run which requires AccessExclusiveLock.
