Agreed.  The documentation is suggestive of this limit:

# CREATE TABLE n (c numeric(1001,0));
ERROR:  NUMERIC precision 1001 must be between 1 and 1000
LINE 1: CREATE TABLE n (c numeric(1001,0));

However, that's indeed just a limit of the numeric typmod representation, not
the data type itself.  An unqualified "numeric" column hits no such limit.
