In cube data is detoasted at least 4 times before going to
g_cube_internal_consistent(), including once in g_cube_consistent()
But I'll address that in another patch.
Here's new version of the patch, with:
1. Corrected docs
2. Any combination of dompress\decompress\fetch is allowed
3. (Existence of fetch) or (absence of compress) leads to IOS
The last point seems counterintuitive, but I do not see anything wrong.
Best regards, Andrey Borodin, Octonica.
