Hi, I managed to recreate a simple example that's crashing postgres. I am running on a DEC Alpha with Digital Unix Version 4.0d and Postgres 3.2. I tried this example several times, on several databases and it crashes every time. We also re-built Postgres and still did not work. Here's the example. Can anybody please help? Thank you...
