alternative DB locations

Hi,

I'm just trying the three lines from the initlocation online man page
(version 7.0.2) as postgres. postgres owns the locations, and initlocation
runs OK, but it don't like to create the DB.

omni.ac.uk> whoami
postgres
omni.ac.uk> export PGDATA2=/public_searchable_0
omni.ac.uk> initlocation PGDATA2
The location will be initialized with username "postgres".
This user will own all the files and must also own the server process.

Fixing permissions on pre-existing directory /public_searchable_0
Fixing permissions on pre-existing directory /public_searchable_0/base

initlocation is complete.
You can now create a database using
  CREATE DATABASE <name> WITH LOCATION = 'PGDATA2'
in SQL, or
  createdb <name> -D 'PGDATA2'
from the shell.

omni.ac.uk> createdb 'testdb' -D 'PGDATA2'
ERROR:  The database path 'PGDATA2' is invalid. This may be due to a
character that is not allowed or because the chosen path isn't permitted
for databases
createdb: database creation failed


The shell is bash. What am I missing please?

Cheers,

Bob
