Thanks all for your response,
$du -h $MY_DATA/base/$BASE_OID/ returns 162GB but when I execute this query:
SELECT stats.relname
AS table,
pg_size_pretty(pg_relation_size(statsio.relid))
AS table_size,
pg_size_pretty(pg_total_relation_size(statsio.relid)
- pg_relation_size(statsio.relid))
AS related_objects_size,
pg_size_pretty(pg_total_relation_size(statsio.relid))
AS total_table_size,
stats.n_live_tup
AS live_rows
FROM pg_catalog.pg_statio_user_tables AS statsio
JOIN pg_stat_user_tables AS stats
USING (relname)
WHERE stats.schemaname = current_schema
UNION ALLSELECT 'TOTAL'
AS table,
pg_size_pretty(sum(pg_relation_size(statsio.relid)))
AS table_size,
pg_size_pretty(sum(pg_total_relation_size(statsio.relid)
- pg_relation_size(statsio.relid)))
AS related_objects_size,
pg_size_pretty(sum(pg_total_relation_size(statsio.relid)))
AS total_table_size,
sum(stats.n_live_tup)
AS live_rows
FROM pg_catalog.pg_statio_user_tables AS statsio
JOIN pg_stat_user_tables AS stats
USING (relname)
WHERE stats.schemaname = current_schema
ORDER BY live_rows ASC;
I obtain 80GB in total_table_size (half of my database), where are
missing data at?
