The application must free the memory referenced by the key or
data pointers when these flags are used. The memory allocated
when these flags are used is the responsibility of the application.

No. Any pointer allocated based on the DB_DBT_MALLOC flag
will never be freed by Berkeley DB.

You can use DB_DBT_REALLOC initially, without first using
DB_DBT_MALLOC.
