Couldn't start postgres, got no logging, ran postgres manually for info-- help?

[Wells Oliver <wellsoliver@xxxxxxxxx>]

I ran:

pg_ctlcluster 9.1 main start

Received:

The PostgreSQL server failed to start. Please check the log output.

But, hey, in /var/log/postgresql, there was absolutely no logging. Nothing. After some googling, I tried:

usr/lib/postgresql/9.1/bin/postgres -D /data/postgresql/9.1/main -c config_file=/etc/postgresql/9.1/main/postgresql.conf 

From the command line, which spit out to the terminal:

2013-07-12 02:04:05 GMT [30091]: [1-1] FATAL:  data directory "/data/postgresql/9.1/main" has group or world access

OK, so where the heck did this error message go when I was running pg_ctlcluster? It would have saved me a lot of time.
