Thats interesting since "ldd initdb" and "ldd pg_ctl" show that there aren't any
.so's needed. Have you tried using the debugger to see whats is causing the fault.

If you are trying to build a "runtime" (Linux and PostgreSQL running live from a
CD) you might want to use install a minimum files system first and then merge
that filesystem that into something like the Slackware disc 2 CD. I've done
that before to make customized runtime/recovery CD's.

For PostgreSQL, you'd need a way to put it on a filesystem that it thinks is
writeable so you'd probably need a kernel that supports a very large ramdisk.
I'm just guessing since I've never attempted to put PostgreSQL on runtime CD but
this has been discussed before so maybe someone else has had some success.
