Timestamp bug WAS: Problem with restore on upgrading to 7.1

owl=# select '2001-05-01 20:57:59.999-04'::timestamp;
?column?
---------------------------
2001-05-01 20:57:60.00-04
(1 row)

owl=# select version();
version
-------------------------------------------------------------------
PostgreSQL 7.1 on i686-pc-linux-gnu, compiled by GCC egcs-2.91.66
(1 row)

So it appears this is a bug in 7.1 as well. The problem is in
postgresql-7.1/src/backend/utils/adt/datetime.c line 2099:
sprintf((str + 17), ((fsec != 0) ? "%05.2f" : "%02.0f"), sec);

..which just tells sprintf to round the seconds. Line 2137 should also
be fixed.

When this is fixed the fix should be backported to 7.0.x so people can
dump for upgrading to 7.1.x.
