attached to this mail is a patch from a colleague that makes
PostgreSQL-7.0.2 run on Linux for the Intel-IA64 architecture. It alsofixes a bug in the configure scripts that caused configure to fail onthe fcntl(F_SETLK) test.This fix triggered a bug in the fcntl(F_SETLK) code of the Linuxkernel when used on unix domain sockets resulting in postmaster tosegfault immediately after startup. There is a fix available andincluded in the kernel that will be on SuSE Linux 7.0, but kernels <=2.2.16 still have this bug.Reinhard Max
