Hi, everyone. Samuel wrote:
What is work_mem set to? If all the other values were set so low, I'd expect work_mem to also be small, which could be causing all kind of disk activity when steps don't fit into a work_mem segment.
I just checked, and work_mem is set to 30 MB. That seems a bit low to me, given the size of the database and the fact that we're doing so much sorting and subselecting. Am I right that we should push that up some more?
