Prior to this patch, an assertion was throwed if a tuple with an
incorrect id was inserted into the _priv system space. This bug
appeared only in the debug build.

Closes #6295

Hi! Thanks for the patch!

See 4 comments below.

2. Could you please add a changelog?

3. Shouldn't the message be like a comment? Describing the correct
behaviour. It is printed always along with ok/no ok in the tap output.
So it should be about what is expected.

4. Why? The test does not pass in release?

It does, however in release build nothing will change. At least at the first

    schema: remove assert on wrong insert into _priv
    
    Prior to this patch, an assertion was throwed if a tuple with an
    incorrect id was inserted into the _priv system space. This bug
    appeared only in the debug build.
    
    Closes #6295

Thanks for the patch!

I think it's better to return NULL in this case.
And set the diagnostics accordingly.
And check for schema_find_name results in alter.cc

schema_find_name is the place where we already know there's no such 
space, or
function, and so on.

So priv_def_check should fail right at schema_find_name, not later.
