I am sorry for that, but I made two different installations and I was
messing up with various inputs.

Actually, the installed versions are below
*postgresql-8.3*
*Ubuntu 8.10 with 2.6.27 Kernel*
*and its an 32Bit O/S*

pgsql$ SELECT substring(B'1111000000000001' from 5 for -2);
ERROR:invalid memory alloc request size 4244635647

I just wanted to know how severe it is and how it can effect the database to
result Memory Corruption/DoS.

Please help me in making the point clear.

Thanks again.
