Hm. It looks like pg_ctl found a PID file pointing to a non-existent
process, which is a bit like what you're seeing initdb do.
I wonder whether this is somehow caused by conflicting settings for
PGDATA. Do you have a setting for that in your environment, or .bashrc
or someplace, that is different from what you're trying to use?
