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
