+1 for doing something against these long lines.

Rather than padding up to the terminal's width, we could simply end
the line after the "-[RECORD N]-" marker, with the idea that the
rest of it does not add much to readability anyway.
And when writing into a file as opposed to a terminal, getting rid of
these lines is useful too.

In that case, your example could be displayed like this:

=> \pset expanded on
=> \pset border 1

=> select n, repeat('x', n) as long_column_name from unnest(array[42,210])
 as n;

-[ RECORD 1 ]-
n         | 42
long_column_name | xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-[ RECORD 2 ]-
n         | 210
long_column_name |

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

=> \pset border 0
=> select n, repeat('x', n) as long_column_name from unnest(array[42,210])
 as n;

* Record 1
n         42
long_column_name xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
* Record 2
n         210
long_column_name

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
