pg_restore

Hi,

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:

pg_restore: connecting to database for restore
pg_restore: dropping DATABASE mydb
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 4312; 1262 16384 DATABASE
mydb mydb
pg_restore: [archiver (db)] could not execute query: ERROR: cannot drop
the currently open database
Command was: DROP DATABASE IF EXISTS mydb;

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

Thanks,
Ram
