postgres process using excessive CPU

I did mention it in my followup to the RMA, so we'll see.

Unfortunately this unit is in a remote datacenter and I had to travel to handle the swap. I replaced it and made sure it booted up and then left, assuming it would all be okay and I updated the config later that night. Getting a different RMA would have been troublesome for my schedule so I'm glad I was able to figure it out, and hopefully it's helpful in the future. :)
