Around a year ago we made some big changes to the ETL process in our Oncology data warehouse. The change allowed us to greatly reduce bloat in the data warehouse indexes and tables. The only problem, this system uses lots and lots and lots of temp tables. The result of this, we are now bloating the PostgreSQL catalog table pg_catalog.pg_class a substantial amount. Fortunately the community was a great help and some e-mails on the PostgesSQL e-mail list pointed to a solution.
The simple solution I decided to take, just put this into a nightly cron job:
VACUUM FULL pg_catalog.pg_class;
REINDEX TABLE pg_catalog.pg_class;
Now pg_attribute could not be cleaner, I love simple solutions.

We are facing an immediate need to refresh and expand some of our iSCSI storage we are running our PostgreSQL instance on. I am open to just about anything but I wondered if this group would have any suggestions. One item that is a bit unique to our situation is I am not in the need of staggering performance as I am in the need for very cost effective large mounts of storage. For more details on what I am doing: http://www.slideshare.net/AaronThul/this-is-your-postgresql-on-drugs
At the moment I am looking at Sun Storage 7000 Unified Storage Systems or a Dell Equallogic. Would anyone like to suggest other options? Has anyone had any problems with those vendors? Anyone like to share a glowing review or success story?
