I'm wondering where "IF NOT EXISTS" and "OR REPLACE" will meet.
For example, why doesn't your list include CREATE FUNCTION?
I have on my personal todo list to add "OR REPLACE" support to CREATE
AGGREGATE and CREATE OPERATOR. They are kind of like functions, after
all, and CREATE OR REPLACE FUNCTION is clearly widely useful.
I suppose both could be useful, but if we're going to make sweeping
changes, perhaps that should be clarified.
Btw., I also want REPLACE BUT DO NOT CREATE.
