Heikki Linnakangas fe280694d0 Scan GiST indexes in physical order during VACUUM. 
Scanning an index in physical order is faster than walking it in logical
order, because sequential I/O is faster than random I/O. The idea and code
structure is borrowed from B-tree vacuum code.

Patch by Andrey Borodin, with changes by me. Based on early work by
Konstantin Kuznetsov, although the patch has been rewritten multiple times
since his original version.
