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()
