Postgres using 100% of CPU

So it was running fine for most of yesterday after I killed the processes. This morning they’re back, with 8 of those queries running, and a load average of 8.

Is there something I can do about this? Either not have that scheduled task run, or somehow run it manually? If it’s trying to verify the integrity of the database, can I just do that manually so it doesn’t spawn all these processes when the scheduled task runs?
