The problem with dropped relations in REINDEX has been addressed by
1d65416, so I have gone through this patch again and simplified the
use of session locks, these being taken only when doing a REINDEX
CONCURRENTLY for a given partition. This part is in a rather
committable shape IMO, so I would like to get it done first, before
looking more at the other cases with CIC and CLUSTER. I am still
planning to go through it once again.
