Postgres backup & restore

Hello team,

We have a postgres11.2 on docker and we are migrating a kb_rep database from postgres 9.6 to postgres 11.2 via pg_dump/pg_restore
We have created a kb_rep schema in postgres 11.2 also but during pg_restore there is an error "pg_restore: [archiver (db)] connection to database "kb_rep" failed: FATAL: database "kb_rep" does not exist"

See below:

psql (11.2 (Ubuntu 11.2-1.pgdg18.04+1))
Type "help" for help.

Please help on this issue.
