With postgres 14, the checkpoint_completion_target is 0.9 by default and it is 0.5 with previous versions. It makes sense to use the same value for different postgres versions in our tests.
Also max_wal_size = 1GB is quite small for our tests and we increase it to 50GB to prevent checkpoints during tests.
