  Multi-Version Concurrency Control
  MVCC
  
     <database> (MVCC) An advanced technique for improving
     multi-user database performance.
  
     The main difference between multiversion and lock models is
     that in MVCC locks acquired for querying (reading) data don't
     conflict with locks acquired for writing data and so reading
     never blocks writing and writing never blocks reading.
  
     This technique is used in the free software database
     PostgreSQL.
