Yeah, this is an intentional and very ancient behavior:

        appendPQExpBufferStr(&buf,
                             ",\n  (SELECT substring(pg_catalog.pg_get_expr(d.adbin, d.adrelid, true) for 128)"
                             "\n   FROM pg_catalog.pg_attrdef d"

Maybe we should decide that completeness is more important than keeping
the line to some arbitrary width.  But it's operating as designed.
