Do you have an overall plan (besides "make it go faster!") or are you
just trying out the knobs as you find them?

I am a newbie, as you all know, but I am still embarassed asking
this question. I started my tuning career by changing
shared_buffers. Soon I discovered that I was hitting up against the
available RAM on the system. So, I brought the number down. Then I
discovered max_fsm_pages. I could take that up quite high and found
out that it is a 'disk' thing. Then I started increasing
checkpoint_segments,which is also a disk thing. However, setting it
to 25, and then increasing any of the other 2 variables, the
postgresql daemon stops working. meaning it does not start upon
reboot. When I bring shared_buffers or max_fsm_pages back down, the
daemon starts and all is normal. This happens on a 1 GB RAM machine
and a 4 GB RAM machine.
Anyone know what I am doing wrong?
System: FreeBSD 6.1, Postgresql 8.09, 2 GB RAM
