Oh, great catch!

Other tests seem to extract block size using database query like

$primary->safe_psql('postgres',
"SELECT setting::int FROM pg_settings WHERE name = 'block_size';");
or
$blksize = int($node->safe_psql('postgres', 'SHOW block_size;'));

But here we do not have running cluster, so resorting to parsing pg_resetwal seems reasonable.

Thanks!
