We currently check and throw an error if the version loaded in the client is different from the installed extension version, however there is no way to recover from this state in a backend. (There is no way to load the new version as we cannot unload the old and no commands can be effectively run). Now, we instead throw a FATAL error which will cause the client to reconnect so it can load the proper extension version.
