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.
