That's an informative article. I was hoping, however, that it would have
a few details about the effects of the statistics settings on
performance. Which statistics options affect the planner? Do they
potentially affect autovacuum?
Also, a 32-bit machine can only hold so much RAM. If I'm correct, there
are ways to address more memory than that on a 32 bit machine, but I
wonder at what cost? In other words, is it a good idea to address more
than 4GB on a 32 bit machine? If not, is it a reasonable choice to
invest in 64 bit if you want >4GB of RAM? Or are you better off just
spending the money on RAID and staying at 4GB?
