Hm. The diff is clear:
***************
*** 2852,2859 ****
SET SESSION ROLE user_reindex;
ERROR: role "user_reindex" does not exist
REINDEX SCHEMA schema_to_reindex;
- NOTICE: table "schema_to_reindex.table1" was reindexed
NOTICE: table "schema_to_reindex.table2" was reindexed
-- Clean up
RESET ROLE;
DROP ROLE user_reindex;
--- 2852,2859 ----
SET SESSION ROLE user_reindex;
ERROR: role "user_reindex" does not exist
REINDEX SCHEMA schema_to_reindex;
NOTICE: table "schema_to_reindex.table2" was reindexed
+ NOTICE: table "schema_to_reindex.table1" was reindexed
-- Clean up
RESET ROLE;
DROP ROLE user_reindex;

We could store the results in an array instead of a list and apply a
qsort to it, but that would be costly if there are many relations
involved in the reindex. Hence I guess raising client_min_messages to
warning is fine? I'll send a patch in the REINDEX SCHEMA thread,
groupped with a couple of other fixes to problems I just found.
