Re: could not create lock file postmaster.pid: No such file or directory, but file does exist

OK, it is clear to me that I didn't make the best choices setting up this database. :(
I am happy I found this list because I am learning a lot in a very short period of time. :) Thank you all for your tips and comments.

I will definitely move the database to a Linux-system and set fsync to on. I hope this will give me a more stable environment. Furthermore I'll dive into the whole database-backup subject so next time I'll have something to restore if things go wrong.
