Is there anyway to query the free space map and see  how many entries there are for a specific table? 

We are starting to have some performance issues since our upgrade to 8.1 (running 8.1.3).  However I can vacuum one table and the issues are temporarily solved.  I am trying to do some research and would like to know what the fsm looks like before and after I vacuum this table.

Is this possible?

Thanks,

Chris
