You can check this too:
select relname, relpages, reltuples, relkind
from pg_class
where relkind in ('r', 'i')
order by relpages desc limit 20;
Will give you the top-20 tables and their sizes, 1 page is typically
8KB, so you can cross-check if relpages/reltuples is completly off,
this is a good indicator for table/index bloat.
use this query :
select pg_size_pretty(pg_relation_size(oid)) as relation_size,relname,
relpages, reltuples, relkind
from pg_class
where relkind in ('r', 'i')
order by relpages desc limit 20;
output will be much more readeable
