All of this appears to be in order.  I think we need some more
information.  First, what options are you setting?  What is the exact
command you are using to launch pg_autovaccum.  Some output from
pg_autovacuum with debug level set to 2 would be helpful.  Also, what OS
/ compiler are you using?

BTW: are you sure that you have performed enough inserts / updates /
deletes to exceed the thresholds? (debug level 2 will tell you what the
thresholds are.
