Hi Kirill,

The CF entry is still Ready for Committer, but Japin's August 13 review
found that gin_entrypage_items() does not finalize its temporary tuple
descriptor before index_getattr(). With assertions enabled, the new
check added by c456e391138 can fail here.

Could you fold the proposed TupleDescFinalize() call into a new patch
version? I have moved the entry to Waiting on Author for now.

Thank you!

Best regards, Andrey Borodin.
