Could you show the results of this query?:
 
SELECT relkind, oid, relfilenode, reltoastrelid,
       relpages, reltuples
  FROM pg_class
  ORDER BY relpages DESC
  LIMIT 10;
 
Also, just to be sure that all calculations are based on your actual
build, can you show the results of?:
 
SHOW block_size;
 
Have you checked the level of bloat yet?  (Perhaps autovacuum needs
to be made more aggressive.)
