Drat, another good theory down the drain ;-)

I think it's time to start wheeling out the heavy artillery.  Do you
know how to use gdb?  I think we might be able to get some useful info
this way:

1. Start a postgres process running doing the CREATE INDEX.  Use ps to
determine the PID of the backend process.

2. gdb /usr/local/pgsql/bin/postgres (or whereever you keep the
executable).  You will need to run this as the postgres user.

3. In gdb:
		attach PID-of-backend-process
		break exit
		break _exit		(just belt and suspenders stuff)
		cont
(Depending on your system, it might not let you set a breakpoint at
exit, in which case try setting breaks at "proc_exit" and "quickdie".)

4. Wait for backend to fail.

5. If you hit any of the breakpoints, use "bt" to get a backtrace.
Otherwise, gdb should at least tell you what signal caused the program
to terminate ... which will be more info than we have now ...
