Pages = the # of pages being used to store your data. 

Changed = the # of pages that have been modified as a result of your
most recent vacuum.

Empty = pages containing no "live" tuples

Tup = # of "rows" in your table

Vac = # of dead tuples recovered

Keep = # of tuples that the db did not feel it could safely mark/remove
(probably envolved in some type of transaction)

Unused = # of tuples awaiting being reused

elapsed time is the amount of time it took to deal with the given table
