PostgreSQL might beat on the disk subsystem hard enough to show faults
in it, or perhaps it uses enough CPU that the CPU isn't being cooled
properly anymore, etc.
But regardless, that only means that PostgreSQL is a trigger, not an
actual root cause. And it means that you will almost certainly have
problems even after switching database engines.
You mentioned that you're using a hardware RAID controller. There is
always the possibility that the driver for that controller isn't
entirely stable.
If you have an identical box you can drop in place, I highly recommend
that you do so. I'm betting that your problems will disappear after
you do that.
