Hello
Thank you for working on this patch!
I perform some tests and think behavior with partition tables is slightly inconsistent.
postgres=# reindex table measurement;
WARNING: REINDEX of partitioned tables is not yet implemented, skipping "measurement"
NOTICE: table "measurement" has no indexes
REINDEX
postgres=# reindex table CONCURRENTLY measurement;
ERROR: cannot reindex concurrently this type of relation
Maybe we need report warning and skip partitioned tables similar to plain reindex?
This makes more sense for "reindex database" or "reindex schema": as far i can see, concurrent reindex will stop work
afterfirst partitioned table in list.
regards, Sergei
