OK, that's good news, but then those failures need to have a different source.
But interesting enough the problems were all caused by wrong permissions (just
look at the thread I pointed to in dbforums).

I'll ask them, but I doubt I can get hold of them.
Where would the log be stored?

Yes, but the data dir is created *after* the acount is created, correct?

But still: I think it is a much better strategy to *not* put the data dir into
the program directory.

I believe you :)

You mean for security reasons?
Hmm. But isn't that essential to a DBMS to be able to be contacted from the
outside?

Thanks for the feedback. I finally see some people understanding the advantages
Postgres has over other choices, but these situations surely weren't ideal to
promote Postgres which is a bit sad..
