This patch should fix the problem. Doesn't include my previous patch
for repeat(). Again, somewhat off-the-cuff, so I might have missed
something...

test=# select lpad('xxxxx',1431655765,'yyyyyyyyyyyyyyyy');
ERROR: Requested length too large
test=# select rpad('xxxxx',1431655765,'yyyyyyyyyyyyyyyy');
ERROR: Requested length too large

(That's on a Unicode DB, haven't tested other encodings but AFAICT
this fix should still work.)

Cheers,

Neil
