Suppress checking of chmod 700 on data-dir?

[Johannes Konert <jkonert@xxxxxxx>]

Hi postgresql-listmembers,
for a backup-scenario I need to have access to the pgdata-directory as a 
different shell-user, but postgresqul refuses to start if chmod is not 
700 on the directory.

Is there a way to prevent postgres to check the data-dirs chmod 700 on 
startup (and while running) ?

Thanks for your short replies. I could not figure it out in the 
documentation.
