How about something like:
test(5432)aklaver=>\d timestamp_test
Table "public.timestamp_test"
Column | Type | Modifiers
---------+-----------------------------+-----------
id | integer | not null
txt_fld | text |
ts_fld | timestamp with time zone |
ts_fld2 | timestamp(0) with time zone |
test(5432)aklaver=>SELECT ts_fld2,now()-ts_fld2 from timestamp_test order by
now()-ts_fld2 limit 5;
ts_fld2 | ?column?
