Heikki Linnakangas e09b48316c Add index-only scan support to btree_gist. 
inet, cidr, and timetz indexes still cannot support index-only scans,
because they don't store the original unmodified value in the index, but a
derived approximate value.

Tom Lane 8436489c81 Add KNNGIST support to contrib/btree_gist. 
This extends GiST's support for nearest-neighbor searches to many of the
standard data types.

Teodor Sigaev ef770cbb69 Fixes from Janko Richter <jankorichter@yahoo.de> 
- Fix wrong index results on text, char, varchar for multibyte strings
- Fix some SIGFPE signals
- Add support for infinite timestamps
- Because of locale settings, btree_gist can not be a prefix index anymore (for text).
  Each node holds now just the lower and upper boundary.
