Question with pg_restore s exit code when there are warnings

Question

commands:

bin/pg_dump -b -o -Fc -Z 0 -p 5333 -U user template1 -f db.dump
bin/pg_restore -c  -h localhost -p 5333 -U user -d template1 db.dump 

:

• add new tables to the database and take dump

• delete newly added tables

• try to restore the dump file

• recovery completed with code 1, but still the tables are successfully restored.

error in pg_restore:
   pg_restore: [archiver (db)] query failed: err-1: table "test1" does not exist
       Command: DROP TABLE public.test1;
   WARNING: errors are ignored during recovery: 2

Is this the expected behavior for the dump / restore function when adding / removing tables?
