The ir_attachments table has grown quite large (5+ GB). I am currently storing attachments in the database and I know there is an option to store in the file system which works well.
Are there any ill effects to purging attachments from time to time? It seems that OpenERP 7 will just recreate an attachment on demand if it has been deleted. (At least this is the case I've tested with invoices).
Is it safe to delete attachments?
