I didn't realize MVCC was only implemented in Postgres. That's a huge advantage if you're doing anything other than a mostly-read DB.

  If I'm not mistaken (I'm more of a DB2 guy), Oracle implements MVCC too.

    It does, since version 7. MySQL also does under InnoDB or Falcon. Other DB with MVCC are BDB, Firebird, InterBase, SQL Server, Sybase, ZODB, CouchDB or ObjectStore.
