> I did a quick, slightly more complex test. `NULL IS NOT NULL OR a = 24` simplifies to `false OR a = 24`, but that isn't simplified further to `a = 24`. Could that redundant `or false` get in the way of pruning? I tried a test to verify the value of `tf.transformed` for the expression `NULL IS NOT NULL OR a = 24`, and it returned `false`. When `tf.transformed == false`, simplification is skipped in the original code (line 479: `expr = tf.data`), -- This is an automated message from the Apache Git Service.
