Greetings, 

I have an aggregate function which basically concatenates a whole bunch of rows (that would be the sfunc)  and then  wraps it in a header and footer (the finalunc). It is however for fairly large set many orders of magnitude slower than running string_agg and then the finalfunc.

Is there anyway to use the builtin functions say in the aggregate function definition. Or any other way to speed them up?


Regards,
