Christopher Kings-Lynne mentioned :
=> sort_mem = 4096
Reducing sort_mem to 4096 seems to make it run in a reasonable time
again. Any idea why? The database does a whole lot of huge sorts
every day, so I thought upping this parameter would help.
A couple of queries do seem to run slower now that I reduced
The shared buffers still makes a significant difference when I increase it.
