I want to restore the database with a different schema

A quick and dirty way:

1) rename default schema:

alter schema public rename to public_save;

2) create new schema as default schema:

create schema public;

3) restore data

pg_restore -f pub.backup db_temp [and whatever other options]

4) rename schemas according to need:

alter schema public rename to temp_schema;
alter schema public_save rename to public;
