Timestamp accuracy

Hi,

The user manual said the Timestamp type has a microsecond accuracy, but how can
I display the results of a query with microseconds ?
Without formatting the output has an accuracy of 10^-2 second, and with
formatting it is even worse since the formatting strings do not accept anything
under the second.

SQL example:

> create table test_ts (ts timestamp);
> insert into test_ts values ('2001-2-2 00:00:00.123456789');
> select * from test_ts;

ts
---------------------------
2001-02-02 00:00:00.12+01
