DNAMES: Assertion `column_name->length < 255' failed on a column name with length 255 (precisely)

Description

254-symbol string works all right; 256 symbols throw an error; 255 symbols cause the assertion failure.

Test case:

Note: REPEAT function is not needed, it's just more convenient in a test case than a 255-character-long string.
