Hello all -
I was looking for a way to find out how much disk space each table is
using.
I stumbled upon this page ( http://www.ffnn.nl/pages/articles/linux/postgresql-tips-and-tricks.php
) which gave me a query to show the number of disk pages per object.
Given that a page is 8kb, I added these calculated columns to the
query:
SELECT relname, reltuples, relpages,
relpages * 8 AS relpagesKB,
(relpages * 8 )/1024 AS relpagesMB
FROM pg_class ORDER BY relpages DESC ;
Is this correct?
