> can be useful in doing selective
    replication of a local table to a remote database.  It selects a row
    from the local table based on primary key, and then builds a SQL

> command that will duplicate that row, but with
    the primary key values replaced by the values in the last argument.
    (To make an exact copy of the row, just specify the same values for
    the last two arguments.)
