and make sure that this shuts down any subsequent code generation that might
depend on the transformations that were implemented. This fixes a problem

by disallowing query flattening if the outer query is DISTINCT. Without this fix,
if an index scan is run on the table within the view on the right-hand side of the
LEFT JOIN, stale result registers might be accessed yielding incorrect results,
and/or an OP_IfNullRow opcode might be invoked on the un-opened table, resulting
in a NULL-pointer dereference. This problem was found by the Yongheng and Rui fuzzer.
