Looking for aggtranstype = 'anyarray'::regtype would give you a hit list,
but beware that not every one of those was changed. Looking at HEAD,
I see

postgres=# select aggfnoid::regprocedure from pg_aggregate where aggtranstype = 'anyarray'::regtype;
aggfnoid
---------------
max(anyarray)
min(anyarray)
(2 rows)

so you'd want to exclude those. (I guess just skipping ones with oid <
9999 would be enough to skip built-ins.)
