This idea is quite simple: each time we change how an object is cached in the buffer we bump this version (even if we don't change the ABI version). Notes:
librt. We can however use buffer cache layout version to abandon cache files that would result in reading garbage data.librtversion, and make second PR that actually uses this feature.While I am at it I fix a bug in the float deserialization (magic value was not handled).
