Ahh, There might be a problem in the operation method for the reasons 
that the GUI setting of pgAdminIII is more complex than that of slonik.
Then,  to use slonik when being newly set it for the time being, 
I recommend it. 

P.S)
I set the following scripts to your confirming the operation.

Probably, some users should learn the usage of the slon service seeing it.
