If the backend is truncating the result length, I don't see why psql
would decide it needs 12K dashes for the header.  There's something
awfully fishy going on in your machine.

Try something like

regression=# select length((pow(10::numeric, 131071))::text);
 length
--------
 131089
(1 row)

If that gives the right answer then the NUMERIC code is off the hook,
and what you've got is a strange limitation on output column length.
