log message from autovac doesn't include db name

Hello!

I'm running 9.1.11 on CentOS.  I'm getting several messages like this in my logs:
2014-09-12 01:44:25.583 PDT,,,30540,,4dbffb0c.7b5b,5,,2014-09-12 01:41:42 PDT,74/868,0,LOG,55P03,"skipping analyze of ""foo"" --- lock not available",,,,,,

Unfortunately, I have several databases with tables named 'foo'.  I was expecting a db name in the log message;  can someone explain why it's not there?

Thanks!
