Thanks Martijn. \d test Table "public.test" Column | Type | Modifiers id | integer | score | integer | I tried \copy test (score) to test.txt. It works well. But, suppose I want to select rows with score > 20 (just an example). Then,\copy table [ ( column_list ) ] { from | to } filename doesn't help much. Have a nice weekend!
