Magic number is a unique identifier for the data format of dgraph. In 21.09 we have changed the data format of posting lists by bringing in sroar. Running Dgraph with sroar change on older p directory can cause data corruption. This magic number prevents DB to start up if the version is not compatible. (cherry picked from commit 59f6e7a)
