Newly attached version that fixes a rebase conclict. Including a few
small additions:

1. Use foreach_hash in async.c (in recently introduced code from
   282b1cde9ded)
2. Reference foreach_hash in code comments instead of hash_seq_search
3. Add a note about the reason for the double for loop in foreach_hash
   macro code comment (same comment as for foreach_internal in
   pg_list.h)
