I pushed the patch to add the new test after modifying it to also include the change in the generated_stored test, but with it commented out. This is the method that 83ea6c540 introduced. Since a few commits have already put these files out of sync, maybe we should consider having a single test file that we include with \i after doing something like: \set generated_type STORED \set test_generated_stored true \set test_generated_virtual false \i generated_generic.sql and have generated_generic.sql use \if test_generated_(stored|virtual) as and when required. > 2.
