The problem doesn't involve glibc. It has been compiled with LFS support
since way back in early woody development. The only thing the packages
need to do is to properly compile against this support (See Glibc FAQ),
and the user to be running a 2.4.x kernel. If done properly, the
packages still work even with 2.2.x kernels, just not being able to use
LFS.
Hundres of packages are already compiled this way. PostgreSQL is surely
behind the times on this one.
