如何将公共模式恢复到不同的模式

我有一个转储，其中数据和结构位于公共模式中。我想将其恢复到具有自定义名称的架构中 - 我该怎么做？

编辑V 2：

我的转储文件来自heroku，开头如下所示：

@Tometzky 的解决方案不太正确，至少对于 9.2 来说是这样pg_dump。它将在新模式中创建表，但是pg_dump模式限定ALTER TABLE ... OWNER TO语句，因此这些语句将会失败：

postgres=# CREATE DATABASE demo;
\cCREATE DATABASE
postgres=# \c demo
You are now connected to database "demo" as user "postgres".
demo=# CREATE TABLE public.test ( dummy text );
CREATE TABLE
demo=# \d
        List of relations
 Schema | Name | Type  |  Owner   
--------+------+-------+----------
 public | test | table | postgres
(1 row)
demo=# \q
$
$ pg_dump -U postgres -f demo.sql demo
$ sed -i 's/^SET search_path = public, pg_catalog;$/SET search_path = testschema, pg_catalog;/' demo.sql
$ grep testschema demo.sql 
SET search_path = testschema, pg_catalog;
$ dropdb -U postgres demo
$ createdb -U postgres demo
$ psql -U postgres -c 'CREATE SCHEMA testschema;' demo
CREATE SCHEMA
$ psql -U postgres -f demo.sql -v ON_ERROR_STOP=1 -v QUIET=1 demo
psql:demo.sql:40: ERROR:  relation "public.test" does not exist
$ psql demo
demo=> \d testschema.test 
  Table "testschema.test"
 Column | Type | Modifiers 
--------+------+-----------
 dummy  | text | 

您还需要编辑转储以删除架构限定public.test或将其更改为新的架构名称。sed是一个有用的工具。

我可以发誓正确的方法是pg_dump -Fc -n public -f dump.dbbackup then pg_restore进入一个新的模式，但我现在似乎无法确切地知道如何进行。

更新：不，看起来像sed是你最好的选择。看我想用不同的模式恢复数据库
