Do you see if this enum will add new field?
Would it make sense to just have INT value describing the fallback level, 
similar like EXPLAIN_LEVEL?

Thus,
CALCITE_FALLBACK_LEVEL=0 is all exceptions,
CALCITE_FALLBACK_LEVEL=1 is all non-select and unsupported query,
CALCITE_FALLBACK_LEVEL=2 is all non-select query only.
