Guys I need to find out what this is- it's also on my wooden bed racks

The pictures seem to be showing corrosion of aluminum. The finish on the aluminum, whether that be a clear anodize or other lacquer or enamel coating, has failed in spots and is allowing aluminum oxide to form. As you can guess aluminum oxide is white in color.
First find out whether it is mold or not. What you do next depends on this.
Assuming it is mold you need to do two things.
Clean it off - disinfectant/bleach solution should do the job.
Find out why it's forming. This is the important bit as if you just do the first step it will come back.
The usual cause is condensation which in a bathroom means you have insufficient ventilation.
So the ultimate cure is to fit an extractor fan above the bath to remove the steam. You can get ones that wire up to the light circuit and then "run on" after the light is switched off to provide additional ventilation.
It is a possibility that when the previous owner set it up originally they set it up that way for medical problems, like excess stomach acid. I've been told by doctors to raise the head of my bed before, but I never did. He just told me to put wood underneath the feet or wheels at the head of the bed.
If any of the screw holes match up where all the feet rest then try that. If the wood is not drilled out behind the holes you choose then pre-drill them.
