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.
