Question

你能不能在尝试创建这样的表时告诉你原因：

CREATE TABLE IF NOT EXISTS  doc.bgp_communities (

    i             SERIAL PRIMARY KEY,
    comm_name     TEXT NOT NULL,
    comm_value    TEXT NOT NULL,
    label         TEXT NOT NULL,
    used_as       TEXT NOT NULL,
        modified_on   TIMESTAMPZ DEFAULT NOW(),

    UNIQUE        ( comm_value ),
    CHECK         ( (comm_value SIMILAR TO '%:%') OR (comm_value SIMILAR TO '%:%:%') ),
    CHECK         ( used_as IN ('bgp-customer','destination','dtv-peer','free-peer','generic','infrastructure','origin','private-peer','public-peer','traffic-eng','voip-peer') )

) ;

在此之前，我已经按如下方式创建了模式：

ip_spotlight-# CREATE SCHEMA doc
ip_spotlight-# CREATE SCHEMA net
ip_spotlight-# ALTER DATABASE ip_spotlight SET search_path TO doc,net

我收到以下错误消息：

ERROR:  schema "doc" does not exist

你能告诉我我做错了吗？

PS：我的用户“app”配置如下：

app          | Superuser, No inheritance, Create role, Create DB, Replication | {}

修改

app@[local]:5432 ip_spotlight# CREATE SCHEMA doc ;
CREATE SCHEMA
Time: 1.492 ms
app@[local]:5432* ip_spotlight# CREATE SCHEMA net ;
CREATE SCHEMA
Time: 0.641 ms
app@[local]:5432* ip_spotlight# ALTER DATABASE ip_spotlight SET search_path TO doc,net ;
ALTER DATABASE
Time: 1.036 ms

ip_spotlight(# CHECK         ( used_as IN ('bgp-customer','destination','dtv-peer','free-peer','generic','infrastructure','origin','private-peer','public-peer','traffic-eng','voip-peer') )
ip_spotlight(# ) ;

你在命令末尾错过了半冒号，所以你可能没有创建任何架构：

ip_spotlight-# CREATE SCHEMA doc
ip_spotlight-# CREATE SCHEMA net
ip_spotlight-# ALTER DATABASE ip_spotlight SET search_path TO doc,net

应该看：

t=# CREATE SCHEMA doc;
CREATE SCHEMA
t=# CREATE SCHEMA net;
CREATE SCHEMA
t=# ALTER DATABASE ip_spotlight SET search_path TO doc,net;
ALTER DATABASE

postgres：创建表时不存在schema
