Public bug reported:
Two tests from MySQL 8.4's upstream test suite currently fail against amd64v3
during build time -
https://launchpadlibrarian.net/828002466/buildlog_ubuntu-resolute-amd64v3.mysql-8.4_8.4.7-0ubuntu1_BUILDING.txt.gz
The tests are main.subquery_sj_all_bka_nobnl and
main.subquery_sj_mat_bka_nobnl, which fail due to a slight change in
cost of the nested loop left join
FROM ot1 LEFT JOIN ot2 ON ot1.a=ot2.a AND ot1.a IN (SELECT a FROM it3)
LEFT JOIN ot3 ON ot2.a=ot3.a AND ot3.a IN (SELECT a FROM it3);
EXPLAIN
--> Nested loop left join (cost=48.2 rows=288)
+-> Nested loop left join (cost=48.3 rows=288)
...
mysqltest: Result content mismatch
This could be due to a change in optimization or cost approximation, but
should not affect the functionality of MySQL overall. So these tests can
be skipped specifically for amd64v3 during build time to fix the ftbfs
