Avoid failure to open dropped detached partition
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.
