Schema Size - PostgreSQL 9.2
Hi all,
Can you please provide me a Query that tells me how much space is a Schema
in my DB?
I'm using one but don't think it's right....
Show quoted text
SELECT schema_name,
pg_size_pretty(sum(table_size)::bigint),
(sum(table_size) / pg_database_size(current_database())) * 100 as a
FROM (
SELECT pg_catalog.pg_namespace.nspname as schema_name,
pg_relation_size(pg_catalog.pg_class.oid) as table_size
FROM pg_catalog.pg_class
JOIN pg_catalog.pg_namespace ON relnamespace =
pg_catalog.pg_namespace.oid
) t
GROUP BY schema_name
ORDER BY schema_name

There's been a discussion on that recently (like last month)
which can be found in the archive.

This should give you what you need:
SELECT n.nspname as schema,
pg_size_pretty(sum(pg_total_relation_size(quote_ident(n.nspname)||
'.' || quote_ident(c.relname)))) as size,
sum(pg_total_relation_size(quote_ident(n.nspname)|| '.' ||
quote_ident(c.relname))) as size_bytes
FROM pg_class c
JOIN pg_namespace n ON (n.oid = c.relnamespace)
JOIN pg_authid a ON ( a.oid = c.relowner )
WHERE relname NOT LIKE 'pg_%'
AND relname NOT LIKE 'information%'
AND relname NOT LIKE 'sql_%'
AND relkind IN ('r')
GROUP BY 1
ORDER BY 3 DESC, 1, 2;
