I'd add a bit of details:
-- Make sure that 'pragma table_info()' correctly handles tables
-- without primary key.
> +table_info = box.execute('pragma table_info("_vinyl_deferred_delete")')
To ignore statement result as a rule we use underscore:
_ = box.execute(...)
Finally, personally I wouldn't focus on particular '_vinyl_deferred_delete'
system space, but rather create casual space without pk and/or format and
use it in the test. Then we could run it using both engines.
