Hi all,
Trying to understand how can the pg_toast table be 90% of my entire DB?
SELECT nspname || '.' || relname AS "relation",
pg_size_pretty(pg_relation_size(C.oid)) AS "size"
FROM pg_class C
LEFT JOIN pg_namespace N ON (N.oid = C.relnamespace)
WHERE nspname NOT IN ('pg_catalog', 'information_schema')
ORDER BY pg_relation_size(C.oid) DESC
LIMIT 20;
*Results:*
pg_toast.pg_toast_7255249 1581 GBpublic.ja_feedlog 81 GB
*Total DB size: 1.7 TB*
What's going on here? Is there anything I can do to save up some disk space?
