The max size for the shared memory hash table name is SHMEM_INDEX_KEYSIZE - 1 (shared hash table name is stored and indexed by ShmemIndex hash table, the key size of it is SHMEM_INDEX_KEYSIZE), but when the caller uses a longer hash table name, it doesn't report any error, instead it just uses the first SHMEM_INDEX_KEYSIZE chars as the hash table name.
When some hash tables' names have the same prefix which is longer than (SHMEM_INDEX_KEYSIZE - 1), issues will come: those hash tables actually are created as the same hash table whose name is the prefix. So add the assert to prevent it.
