Some of the ideas I can think of are as follows:
1. Combine "SUBSCRIPTION USES INDEX WITH MULTIPLE ROWS AND COLUMNS"
and "SUBSCRIPTION USES INDEX WITH DROPPED COLUMNS" such that after
verifying updates and deletes of the first test, we can drop some of
the columns on both publisher and subscriber, then use alter
subscription ... refresh publication command and then do the steps of
the second test. Note that we don't add tables after initial setup,
only changing schema.
2. We can also combine "Some NULL values" and "PUBLICATION LACKS THE
COLUMN ON THE SUBS INDEX" as both use the same schema. After the first
test, we need to drop the existing index and create a new index on the
subscriber node.
3. General comment
+# updates 200 rows
+$node_publisher->safe_psql('postgres',
+ "UPDATE test_replica_id_full SET x = x + 1 WHERE x IN (5, 6);");
I think here you are updating 20 rows not 200. So, the comment seems
wrong to me.
Please think more and see if we can combine some other tests like
"Unique index that is not primary key or replica identity" and the
test we will have after comment#2 above.
