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.

Nor do I.  Perhaps this question should be floated on -general?
