In my testing between a commercial database that cannot be named and
postgresql, I found max() / min() to be basically the same, even with
where clauses and joins happening.

count(*), OTOH, is a still a clear winner for the big commercial
database. With smaller sets (1 Million or so) both dbs are in the same
ballpark.

With 30+million rows, count(*) took 2 minutes on pgsql and 4 seconds on
the big database.

OTOH, there are some things, like importing data, which are MUCH faster
in pgsql than in the big database.
