Hello
Sorry for late response. I review latest patch version.

I didn't found any new behavior bugs.

reindex concurrenlty can be in deadlock with another reindex concurrently (or manual vacuum (maybe with wraparound
autovacuum)or create index concurrently on same table). But i think this is not issue for this feature, two create
indexconcurrently can be in deadlock too.
 

Just one small note for documentation:

Second index should be idx_ccnew (or idx_ccold), right?

Code looks good for me.
