I am sure that, most of you aware of this. But, for me it's the first time, I accomplished it. As one of my assigned tasks to build a 32-bit instance of postgresql on 64-bit machine, I have followed the below approach. I hope, it will be helpful to others as well, if you got any problems. As an initial step on this task, I have tried to build a sample "c" program using "gcc -m32". Once, I resolved this, I moved to compile the PostgreSQL 9.0.
