Bug reference: 16542
Logged by: Seren_Modz 21
Email address: dylangregory612(at)gmail(dot)com
PostgreSQL version: 12.0
Operating system: Ubuntu 18.04.4 LTS Server
Description:

I'm not sure if it's 12.0 as I installed it with "sudo apt-get install
PostgreSQL" and only know that it is v12.x. Our VPS has a 3x vCore (3.70ghz)
CPU but when we checked HTOP, we noticed that PostgreSQL was maxing out all
3 cores after sorting the list out by CPU Percentage. This is incredibly
high and we don't know why it's being maxed out. You can view the HTOP
results here: https://imgur.com/a/FxByiyX
