Hi, hackers!

There is a memory leak in functions check_application_name() and 
check_cluster_name().
Functions are located in src/backend/commands/variable.c

The leak can be triggered using SQL command: SET 
application_name=new_name;
You can run pgbench with this command for a long time by passing this 
command in file via '-f' flag.

regards,
Tofig
