I'm curious what parameters you guys typically *always* adjust on new PostgreSQL installs. I am working with a database that contains several large tables (10-20 million) and many smaller tables (hundreds of rows). My system has 2 GB of RAM currently, although I will be upping it to 4GB soon. My motivation in asking this question is to make sure I'm not making a big configuration no-no by missing a parameter, and also for my own checklist of parameters I should almost always set when configuring a new install. The parameters that I almost always change when installing a new system is shared_buffers, max_fsm_pages, checkpoint_segments, and effective_cache_size. Are there any parameters missing that always should be changed when deploying to a decent server?
