FUNCTIONS
  diffdb
    Usage:

     diffdb(%args) -> [status, msg, payload, meta]

    Compare two databases, line by line.

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   dbh1 => *obj*

        Alternative to specifying dsn1/user1/password1.

    *   dbh2 => *obj*

        Alternative to specifying dsn2/user2/password2.

    *   diff_command => *str* (default: "diff")

    *   dsn1 => *str*

        DBI data source, e.g. "dbi:SQLite:dbname=/path/to/db1.db".

    *   dsn2 => *str*

        DBI data source, e.g. "dbi:SQLite:dbname=/path/to/db1.db".

    *   exclude_columns => *array[str]*

    *   exclude_tables => *array[str]*

    *   include_columns => *array[str]*

    *   include_tables => *array[str]*

    *   order_by => *str*

    *   password1 => *str*

        You might want to specify this parameter in a configuration file
        instead of directly as command-line option.

    *   password2 => *str*

        Will default to "password1" if "password1" is specified.

        You might want to specify this parameter in a configuration file
        instead of directly as command-line option.

    *   row_as => *str* (default: "json-one-line")

        Compare the result of SQL select query, instead of tables.

    *   user1 => *str*

    *   user2 => *str*

        Will default to "user1" if "user1" is specified.

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
