hi,
I've had an `INSERT INTO x SELECT FROM [...]` query running for more
then 2 days.
Is there a way to see how big x has gotten? Even a very rough estimate
(off by a gigabyte) would be fine.
Best,
Seamus

Try:
SELECT n.nspname as schema,
c.relname as table,
a.rolname as owner,
c.relfilenode as filename,
c.reltuples::bigint,
pg_size_pretty(pg_relation_
pg_size_pretty(pg_total_
pg_relation_size(n.nspname|| '.' || c.relname) as size_bytes,
pg_total_relation_size(n.
CASE WHEN c.reltablespace = 0
THEN 'pg_default'
ELSE (SELECT t.spcname
FROM pg_tablespace t WHERE (t.oid = c.reltablespace) )
END as tablespace
FROM pg_class c
JOIN pg_namespace n ON (n.oid = c.relnamespace)
JOIN pg_authid a ON ( a.oid = c.relowner )
WHERE relname = 'x'
ORDER BY total_size_bytes DESC, 1, 2;
