डेटाबेस ऑब्जेक्ट आकार कार्य का प्रयास करें । एक उदाहरण:
SELECT pg_size_pretty(pg_total_relation_size('"<schema>"."<table>"'));
सभी तालिकाओं के लिए, कुछ की तर्ज पर:
SELECT
table_schema || '.' || table_name AS table_full_name,
pg_size_pretty(pg_total_relation_size('"' || table_schema || '"."' || table_name || '"')) AS size
FROM information_schema.tables
ORDER BY
pg_total_relation_size('"' || table_schema || '"."' || table_name || '"') DESC;
संपादित करें: यहाँ सुविधा के लिए @phord द्वारा प्रस्तुत क्वेरी है:
SELECT
table_name,
pg_size_pretty(table_size) AS table_size,
pg_size_pretty(indexes_size) AS indexes_size,
pg_size_pretty(total_size) AS total_size
FROM (
SELECT
table_name,
pg_table_size(table_name) AS table_size,
pg_indexes_size(table_name) AS indexes_size,
pg_total_relation_size(table_name) AS total_size
FROM (
SELECT ('"' || table_schema || '"."' || table_name || '"') AS table_name
FROM information_schema.tables
) AS all_tables
ORDER BY total_size DESC
) AS pretty_sizes;
मैंने pg_table_size()
मेटाडेटा को शामिल करने और आकारों को जोड़ने के लिए उपयोग करने के लिए इसे थोड़ा संशोधित किया है ।
