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) Michael Glaesemann grzm myrealbox com
