It appears that the line is extended one underscore beyond the width
of the wider of the attribute name and value. Am I missing something?
test=# create table foo (this_is_a_long_attribute text not null,
short_attr text not null);
CREATE TABLE
test=# insert into foo (this_is_a_long_attribute, short_attr) values
('narrow_value', 'this_is_a_very_wide_value');
INSERT 0 1
test=# select * from foo;
this_is_a_long_attribute | short_attr
--------------------------+---------------------------
narrow_value | this_is_a_very_wide_value
(1 row)
