Hi!
I have noticed the novice users are stuck trying to create tablespace
over a directory whose owner is not the system postgres user. They
observed the message "could not set permissions on directory ...:
permission denied".
I want to add patch that prints hint to set required owner for the
tablespace directory if this is the cause of the problem (*errno ==
EPERM* after calling *chmod*).
