[PERFORM] Updating table, precautions?

[Anjan Dave]

Hi there,   We need to update a table of about 1.2GB (and about 900k rows) size. I was wondering if I should let the regular cron job take care of clean up (vacuum db Mon-Sat, vacuum full on Sun, followed by Reindex script), or manually do this on the table followed by the update.   This is what I used to find the table size, which probably doesn’t include the index size. Is there a way to find out size of indexes?   select relpages * 8192 as size_in_bytes from pg_class where relnamespace = (select oid from pg_namespace where nspname = 'public') and relname = 'r_itemcategory';     Thanks, Anjan     ****************************************************************************************** This e-mail and any files transmitted with it are intended for the use of the addressee(s) only and may be confidential and covered by the attorney/client and other privileges.  If you received this e-mail in error, please notify the sender; do not disclose, copy, distribute, or take any action in reliance on the contents of this information; and delete it from your system.
