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. Joe Conway |
