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.

I made the same mistake you did, by doing "-d mydb".  You need to specify the postgres database.

This works for me:
export PGUSER=${RUN_USER}
export PGHOST=localhost
DB=mydb
pg_restore -xOvcC --if-exists --jobs=${JOBS} -d postgres ${DB} 2> ${DB}_restore.log

But it just occurred to me that I used directory backups, not custom backups, so this probably won't work for you.
