Re: I probably don't understand aggregates.

But how can I get my wrapper function to evaluate the aggregate on the
whole table and work with the result afterwards?

Or do I need to change the aggregate?

​I do not follow but...

SELECT myWrapper(agg_output) FROM (

SELECT myAgg(x) AS agg_output FROM test

)​ agg_subquery;

It is not clear why you need both an aggregate and a wrapper...
