Hmm. That sounds pretty broken. Does anything get logged in the
postmaster's log file (wherever you redirected its stdout/stderr to)?
Does a core file get created? (Look for a core file both in the
postgres data directory and in its subdirectories.) If there is a
core file, extracting a backtrace from it with gdb or your favorite
debugger would help us figure out what's wrong.

My first guess is some sort of configure/build foulup. What kind of
system are you running on? Which template did 'configure' pick?
