client file check

Hi everyone...

 
Does anyone know how the client file check works?  My client is running
as a non-privileged user and trying to check a file in the Postgres
directory, which of course it doesn't have access to.  I would let it
use sudo if I could, but adding sudo to the ls command in the client
config doesn't do anything.  So what mechanism does the client use to do
file checks?

 
Thanks,
