It turns out this patch is not necessary, since #5048 accomplished the same goal. String expressions on the __time column work by first building a base primitive selector, and #5048 optimizes those. That optimization ends up being inherited by the dimension selector.
#6599 extends the optimization to apply to Long columns that are not __time.
