- Update to 12.02.0000:
  * Add a new *Display Optional Error Message* option.
    This option allows to display error messages other than primary
    one. Also add documentaition about the option and
    *Numeric as* option.
  * Handle notice messages in libpq_bind_and_exec().
    Sets and resets a notify receiver around PQexecParams() or
    PQexecPrepared().
  * Ignore PQtransactionStatus PQTRANS_ACTIVE in
    LIBPQ_update_transaction_status(). PQTRANS_ACTIVE isn't a
    transaction status.
  * Improve execution of parameterized SQL statements with arrays
    of parameters by sending chunks of SQL statements.
    If SQL_ATTR_CURSOR_TYPE of an statement is
    SQL_CURSOR_FORWARD_ONLY, SQL_ATTR_CONCURRENCY is
    SQL_CONCUR_READ_ONLY and extended protocol isn't used, the
    batch execution of the statement is possible. A new option
    Batch Size was introduced for such cases.
    Batch Size: Split an array (of parameters) into chunks of
    Batch Size to execute statements. The last chunk may contain
    less than Batch Size elements. Setting 1 to this option forces
    the current one by one execution.
    Also turn off use_server_side_prepare option temporarily when
    batch executuion is possible.
  * Change SC_execute() so that it returns a return code which is
    not affetced by the preceding results. It's necessary for
    batch execution with arrays of parameters.
  * Add a new option IgnoreTimeout.
  * Some tools issue issue SQLSetStmtAttr(.., SQL_ATTR_QUERY_TIMEOUT,,)
    internally and sometimes it's difficult for users to change the
