Why the heck do you need 20 *thousand* columns?
Assuming, though, that you know what you're doing, and the design
isn't horribly botched, then arrays might be what you want.
Normalizing the table might be better, and vertically partitioning
it would be a big performance win if you don't need all 20
*thousand* columns at the same time.
