something I find PC very slow, and I notice that some postgres-related processes like mpool (the user is in fact postgres), are using 100% of CPU, even using all the cores, and I have to kill them. Why is that so?
thank you

This is a malicious attack. If you're using postgres 9.1 or less UPDATE your postgres installation. Check your logs and you will find that scripts has been executed on your machine.
As per request, i've experienced this kind of attack on Postgres 9.1 on Ubuntu 14.04 LTS
Check this post for information about this vulnerability.
Easy solution is to check your log for IP information and block it in your IPTABLE. Better solution is to update your version of Postgres if your environment allows for it.
