Hi,


To kill the process and session you can do like follows:



(1) Edit  " pg_hba.conf  " file which is in your data directory and  at the
bottom of the file add a line as follows:



 host all all <client IP address/32>  reject



(2)And reload the database.

pg_ctl –D <your data directory path> reload



(3)After that run the following command:



$ pg_ctl -D <your data directory path> kill TERM <procpid>



Thanks & Regards,
Raghu
