Hi,
 
 Can any one tell me whats the effect of the below Query
 
SELECT substring(B'1111000000000001' from 5 for -2);
SELECT substring(B'1111000000000001' from 4 for -3);
 
its observed that there's an Error "invalid memory alloc request size 4244635647"
 
What will actually happen to the Postgresql database.
 
I am using Postgresql 8.4.3 on Ubuntu 8.04
 

 
I can reproduce this with 8.4.*2* on Ubuntu 10.04 32-bit (postgres built from src) but *not* with 8.4.*3*. Can you double check it is 8.4.3 you are using? and if so tell us whether you are using 32 or 64 bit Ubuntu!

Cheers

Mark
