When a partition is detached and immediately dropped, a prepared statement could try to compute a new partition descriptor that includes it. This leads to this kind of error: ERROR: could not open relation with OID 457639 Avoid this by skipping the partition in expand_partitioned_rtentry if it doesn't exist. Noted by me while investigating bug #18559. Kuntal Gosh helped to identify the exact failure. Backpatch to 14, where DETACH CONCURRENTLY was introduced.
