I have a naive question. LinuxPPC is, AFAIK, basically RedHat recompiled for PPC with some new device drivers written for it and a few bells and whistles (like its own graphical installer) thrown in. I would have thought that porting Postgres to LinuxPPC would be a simple as a recompile and that it ought to run as well as it would on RedHat for x86. What am I missing?
