I know that I'm late to the party, but a small suggestion: Run
"initdb" with "strace" (truss on Solaris) and examine the syscalls
made.  It should show you, conclusively, what files are being
"open"ed, "unlink"ed, etc...

Example:

strace -o /tmp/x initdb -D /tmp/data-1
grep -E '^(open|unlink)' /tmp/x
