I have THREE  summary tables derived from "stats" with different levels 
of aggregation. They work quite fast,  But:

1) Summary tables grow too
2) There are requests which cannot be predicted, so they involve the 
"stats" table itself.

So I am still interested in PostgreSQL's ability to deal with 
multimillon records tables.
