That gave me an idea. I thought that autovacuum is doing it right, but I
issued a vacuum full analyze verbose , and it worked all the day.
After that I've tweaked memory settings a bit too (more fsm_pages)
Now:
staging=# SELECT count(*) from infx.infx_product;
count
---------
3284997
(1 row)
Time: 1301.049 ms
As I saw the output, the database was compressed to 10% of its size :)
This table has quite big changes every 4 hour, let's see how it works.
Maybe I'll have to issue full vacuums from cron regularly.

This went to 10% as well, now it's around 156000 pages.
