On my db server I have noticed a very high CPU usage of process:
*postgres: stats collector process*

It is not below 50% of CPU. (Info from htop).

What is best way to decrease CPU usage of this process?

This is a known issue when you have a large number of databases with a large number of objects each.

It will be fixed in 9.3.  In the meantime you can perhaps increase autovacuum_naptime, but that has tradeoffs.

Cheers,

Jeff
