Re: cluster de datos

mira a ver con eso
SELECT distinct datname as "nombre de la base",pg_size_pretty(pg_database_size(datname))
as "Tamaño de la base" from pg_stat_activity ;
o a tablas por separado

SELECT nspname, relname,
pg_size_pretty(tablesize+indexsize+toastsize+toastindexsize) AS totalsize
FROM
(SELECT ns.nspname, cl.relname, pg_relation_size(cl.oid) AS tablesize,
COALESCE((SELECT SUM(pg_relation_size(indexrelid))::bigint
FROM pg_index WHERE cl.oid=indrelid), 0) AS indexsize,
CASE WHEN reltoastrelid=0 THEN 0
ELSE pg_relation_size(reltoastrelid)
END AS toastsize,
CASE WHEN reltoastrelid=0 THEN 0
ELSE pg_relation_size((SELECT reltoastidxid FROM pg_class ct
WHERE ct.oid = cl.reltoastrelid))
END AS toastindexsize
FROM pg_class cl, pg_namespace ns
WHERE cl.relnamespace = ns.oid
AND ns.nspname NOT IN ('pg_catalog', 'information_schema')
AND cl.relname IN
(SELECT table_name FROM information_schema.tables
WHERE table_type = 'BASE TABLE')) ss
ORDER BY tablesize+indexsize+toastsize+toastindexsize DESC;

buenas noches:

Quisiera saber si existe alguna consulta o vista que muestre el espacio en disco que ocupa el cluster de datos de postgresql...

saludos
