Hi Josh, at the moment the server is unreachable so I can’t calculate sizes. I run all of my test both with all data loaded into Postgres and with no data loaded (except from the single 20mln rows table with relative indexes). To give you an idea, with all data loaded into Postgres with indexes the space occupied is approximately 1.2-1.5TB and free space on is about 800GB. Many thanks.

Or it that's a bit much to get, how much disk space is occupied by your database in total? -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
