This is missing a catversion bump, due to the changes in view
names. Noticed that because I got errors like
-- There must be only one record
select count(*) = 1 as ok from pg_stat_wal;
- ok
-----
- t
-(1 row)
-
+ERROR: function return row and query-specified return row do not match
+DETAIL: Returned row contains 5 attributes, but query expects 2.
-- This is to record the prevailing planner enable_foo settings during

when running tests against a pre-existing cluster after rebasing a
