Comment 28 for bug 162517

How do I have to put it:

create_db works fine. The database gets created
pg_createcluster works fine and even starts (magically as I have not read the code) the database server
it is the init script that checks for a nonexistent directory

only postgresql_common is created.

If you insist that locales are the fault, how could I possibly have created a database and even used it from OpenOffice.
The locales have NOTHING whatsoever to do with it.

btw: I even tried the sudo locale-gen as you suggested. Remove Postgresql, install Postgresql same nonexistent directory and broken startup script.

I get the feeling that you prefer spending time discussing instead of fixing.
