Can't restart statistics collection and autovacuum

Hi Guys.
Yesterday, the database server was rebooted and database wasn't shut
down properly.
When it went back online, the following messages showed up:
2014-03-13 08:46:08 UTC LOG: 08006: test message did not get through
on socket for statistics collector

2014-03-13 08:46:08 UTC LOG: 00000: database system was interrupted;

I enabled the track_counts option, but when I checked it, it still shows
as "off".
I have 2 questions:
1. Any ideas how to fix this? I've googled it and check this list and
tried everything so far with no results.
2. Any link to a script I may post on rc6.d to avoid this mishap in the
future?

PostgreSQL version is 9.1.3
OS: Ubuntu 11.10 (GNU/Linux 3.0.0-12-virtual x86_64)
