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;
