You've unfortunately asked on the wrong list about this. pgsql-hackers
is intended mainly for discussion related to the source code of
PostgreSQL, so this is off-topic for it. The people who like to argue
about the best way to implement aggregates and the like are on the
pgsql-performance list. You'd be more likely to get detailed responses
if you asked this question there. That group loves to talk about how to
design things for other people.
