Depends too much on your riding style, your weight and the type of trails and how aggressive.
I weigh 150lbs, trail is rutted chalk with plenty of flint, some mud areas, and plenty of loose stuff. Mainly ride XC with aggresion and speed on the downhills. Fairly stiff 80mm suspension, so 50lbs front and rear. Next bike same style of riding, far faster downhill speed, and all up weight of 400lbs( Ok its a tandem) This cannot be run at less than 60lbs rear and even at that snakebites occur.
At 20lbs you will find that the rear tyre will be trying to roll off the rim on corners, and I would not be surprised to find rim damage. If you are a light rider, ride carefully, 30psi f and rear is possible, but hit any lump or hole at speed with these pressures on hard ground and Pssssssss-
