Session 1 as superuser:
CREATE USER u1;
CREATE SCHEMA u1 AUTHORIZATION u1;
GRANT ALL PRIVILEGES ON SCHEMA public TO u1;
Session 2 as u1:
SET search_path= "$user", public;
CREATE TABLE u1.x(t) AS SELECT 'data in u1.x';
CREATE TABLE public.x(t) AS SELECT 'data in public.x';
SELECT t FROM x; -- uses u1.x
Session 1 as superuser:
ALTER ROLE u1 RENAME TO u2;
Session 2 as u1:
SELECT CURRENT_USER; -- shows u2
SHOW search_path; -- $user, public
SELECT t FROM x; -- UNEXPECTED: uses u1.x still
SET search_path = public;
SET search_path TO default;
SELECT t FROM x; -- uses public.x
The fix is simple, attached.

Is that something that should have an isolation test?

Good idea, attached.
Is there any logical ordering or grouping in the isolation_schedule? I
just added it at the end.

It looks like folks try to group related tests, but I don't sense any
strict ordering. It's probably fine to add it to the end. Maybe we should
alphabetize the list someday (/me braces for collation jokes).

Isolation tests have been added over the years in the order that a
committer and/or author saw fit at the point when it was added. There
has never been any kind of strict ordering, but there may be locations
where having a new test makes more sense than other locations.
