[ClusterLabs] crm_attribute bug in 1.1.15-rc1

[Jehan-Guillaume de Rorthais]

ok, you were trying with the attribute name. I wrote you had a use the
**resource** name.

Your command should be (again):

  crm_master -r pgsqld -N $HOSTNAME -Q

Or simply this if you want to check the score on the local node:

  crm_master -r pgsqld -Q

Moreover, you should really consider doing some cleanup in your attributes,
"pgsql-data-status" and "maintenance" definitely does not comes from the PAF
project.
