A quick look at the current final state of the regression database
says
regression=# select indexrelid::regclass, indrelid::regclass from pg_index where indnatts != indnkeyatts;
indexrelid | indrelid
---------------------+-------------
covidxpart1_a_b_idx | covidxpart1
covidxpart_a_b_idx | covidxpart
covidxpart2_a_b_idx | covidxpart2
covidxpart3_a_b_idx | covidxpart3
covidxpart4_a_b_idx | covidxpart4
(5 rows)
So we've got *some*, but it sure looks like they were all added by the
patch to fix covering indexes for partitions. I'd want to see some for
plain-table cases as well.
