Обсуждение: pgsql: Fix incorrect IndexOptInfo header comment

Fix incorrect IndexOptInfo header comment

The comment incorrectly indicated that indexcollations[] stored
collations for both key columns and INCLUDE columns, but in reality it
only has elements for the key columns.  canreturn[] didn't get a mention,
so add that while we're here.
