When planning queries with ON CONFLICT on partitioned tables, the indexes to consider as arbiters for each partition are determined based on those found in the parent table. However, it's possible for an index on a partition to be reindexed, and in that case, the auxiliary indexes created on the partition must be considered as arbiters as well; failing to do that may result in spurious "duplicate key" errors given sufficient bad luck. We fix that in this commit by matching every index that doesn't have a parent to each initially-determined arbiter index. Every unparented matching index is considered an additional arbiter index. Closely related to the fixes in bc32a12e0db2 and 2bc7e886fc1b, and for identical reasons, not backpatched (for now) even though it's a longstanding issue.
