Attached patch based on:
http://www.postgresql.org/message-id/CAPpHfdssY+qEPDCOvxx-b4LP3ybR+qS04M6-ARgGKNFk3FrFow@mail.gmail.com

and adds selectivity estimation functions to @@ (port from tsquery). Now we
support &&, @>, <@ and @@.
In addition it was written migration to version 1.1 intarray. Because of what
this patch requires my other patch:
http://www.postgresql.org/message-id/14346041.DNcb5Y1inS@dinodell
