Revisit items marked 'NO' in sql_features.txt

Hi,

While reviewing sql_features.txt, found a few items marked NO ('Not
supported') whereas, at the outset, they seemed to be supported. Apologies,
if this is already considered and / or still marked 'NO' for a reason, but
a list of such items mentioned below:

F202 TRUNCATE TABLE: identity column restart option NO

F263 Comma-separated predicates in simple CASE expression NO

T041 Basic LOB data type support 01 BLOB data type NO

T051 Row types NO

T174 Identity columns NO

T176 Sequence generator support NO

T177 Sequence generator support: simple restart option NO

T522 Default values for IN parameters of SQL-invoked procedures
NO

T571 Array-returning external SQL-invoked functions NO
