My comments:
# New test class needs to be added to a test suite
# Let's try avoid repetitive operations during extraction, such as list lookups
({{AST.child(...)}}) and descriptor creation
# Let's make sure that optimization works for both {{x > 1 AND x < 10}} and {{x
< 10 AND x > 1}} cases.

> If there is a range condition on affinity column of integer type, we may try
> to extract partition info from it in a way similar to IN clause [1]:

> {{x > 1 and x <= 5}} -> {{x IN (2, 3, 4, 5)}}
