    Modified pgbench for Postgres-XC.
    
    By default, it will use branch id to distribute by, and also include it in the queries.
    This allows for better multi-node scalability.  For this configuration, we do not
    have to worry about implicit two phase commits occurring.
    
    If running in either initialization or execution mode, alternatively a new option
    -k may be used (-k = "key" = no branch id).
    
    If included with -i, tables are distributed according to their primary key.
    This means we will see a lot of two phase commit activity over multiple data nodes.
    
    Similarly, if -k is included when running tests, branchid (bid) will NOT
    be used as part of the DML statements. This helps us measure the impact of 2PC.
