pg_restore

I have a custome database called mudb along with default databases in my postgresql cluster, i am trying to restore mydb from a custom format pg_dump file, what is the procedure to do it?

psql -t -h localhost  -U ${RUN_USER}  -c "SELECT pg_terminate_backend(pg_stat_activity.pid) FROM pg_stat_activity WHERE pg_stat_activity.datname = 'mydb' AND pid <> pg_backend_pid();"

pg_restore" -h localhost  -U ${RUN_USER}  -d mydb -j "${JOBS}" -x -O -C -c --if-exist -v pgdump.dump 

But i am getting below error:

So what is the best way to restore? I am using 9.6 version.

Thanks,

Ram
