## How to debug disk occupation in postgresql
|
||
|
|
|
||
|
|
- get a database oid number from `ncdu` in `/var/lib/postgresql`
|
||
|
|
- reconcile oid number and db name with : `select oid,datname from pg_database where oid=18595;`
|
||
|
|
- Then in database : `select table_name,pg_relation_size(quote_ident(table_name)) from information_schema.tables where table_schema = 'public' order by 2;`
