No one commented on the choice of name, so the attached patch changes
the name of split(text,text,int) to split_part(text,text,int) per
Hannu's recommendation above. This can be applied without an initdb if
current beta testers are advised to run:

   update pg_proc set proname = 'split_part' where proname = 'split';

in the case they want to use this function. Regression and doc fix is
also included in the patch.
