I found it is not so difficult as I expected; patch attached. Now it copies
comments on indexes and columns of the indexes on INCLUDING COMMENTS.
Regression test and documentation are also adjusted. Please review around
chooseIndexName() and uses of it.
The codes becomes a bit complex and might be ugly because we will have some
duplicated codes; "pg_expression_%d" hacks and uses of ChooseRelationName()
are spread into index.c, indexcmds.c and parse_utilcmd.c.
