Hi,
Also you might want to check the logging settings and log file sizes if logging is enabled. Sometimes due to some issues in database, the number of log file entries can be a lot leading to large log files.

Priyanka

Hi,
Here's a query to list individual table sizes:
select
t.tablename as "object",
pg_size_pretty(pg_relation_size(cast(t.tablename as text))) as "data",
pg_size_pretty(pg_total_relation_size(cast(t.tablename as text))) as "total"
from
pg_tables t
where
t.schemaname = 'public'
order by
pg_total_relation_size(cast(t.tablename as text)) desc
I think the last column includes index sizes.
Running this repeatedly over time should show what's growing.
cheers,
raf
