 Segmentation fault was found after testing the given command(There is
an extra '/' between 'new_standby2' and '-P') '$ gdb --args
./pg_subscriber -D ../new_standby2 / -P "host=localhost
port=5432 dbname=postgres" -d postgres'
While executing the above command, I got the following error:
pg_subscriber: error: too many command-line arguments (first is "/")
pg_subscriber: hint: Try "pg_subscriber --help" for more information.

Program received signal SIGSEGV, Segmentation fault.
