The idea of coding IN operator with a short list on the RHS as an OR expression

turns out to be helpful. If the list is of length 1 or 2, the OR expression
is very slightly faster, but the ephemeral table approach is clearly better for
all list lengths greater than 2. Better to keep the code simple.
