I was surprised to discover that

Is this an oversight, or is there some reason I missed?
Its not an oversight: but whether it is easily accomplished, or worthy of the effort, is a different matter.
Yes, I know I can do:
DROP AGGREGATEIF EXISTS
CREATE AGGREGATE
But this triggers a NOTICE. Is there any convenient way to replace a (possibly) existing aggregate function without triggering a NOTICE?
