Yeah, that's my reaction. We could add "compute_query_id = off" to
the database-level settings set up by pg_regress, but that cure seems
worse than the disease. It would make it impossible to run the
regression tests with pg_stat_statements loaded, which you might wish
to do (just ignoring the bogus test failures) as a way of testing
pg_stat_statements.
