Kevin Fenzi 6052756805 postgresql_server / db-koji01: Adjust a bunch more for performance.
The current settings cause database dumps to drive the load way up
and make the entire application slow, so we need to adjust.
Using pgtune, these values might well be better.

shared_buffers + effective_cache_size should = total memory.
random_page_cost should be lowered a bunch since we are on ssds there.
1.1 is only slightly more than 1.0 for sequential.
effective_io_concurrency should also be raised a bunch for ssds.
a few other values should be higher based on memory.
