There's a BF failure with just these changes [0]. But IMO it's unrelated.
There are 2 failed tests:
1. 'activeslot slot invalidation is logged with vacuum on pg_authid' is very similar to what is discussed here [1]
2. '+ERROR: tuple concurrently deleted' in injection_points/isolation seems to be discussed here [2]

Thanks!

Best regards, Andrey Borodin.
