We should first check that primary key is not NULL.

Closes #4745

Hi! Thanks for the fixes!

It is not a review. I just wanted to say that I am going to
spend less time on reviewes to the end of this week due to
intensive preparations to FOSDEM. I will get back to your
patches as soon as I can, I didn't forget.

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.

I agree, inserted your version.

Fixed.

I rewrote tests, new diff:

+test_run = require('test_run').new()
+engine = test_run:get_cfg('engine')
+--
+-- Make sure that 'pragma table_info()' correctly handles tables
+-- without primary key.
+--
+T = box.schema.create_space('T', {         \
+    engine = engine,                       \
+    format = {{'i', 'integer'}}            \
+})
+_ = box.execute('pragma table_info(T)')
+T:drop()
