你在哪里可以找到 ubuntu 14.04 上 postgres 9.3 中的 citext 模块？

Question

所以我正在尝试使用 citext，但它似乎是来自 ubuntu 14.04 postgres 安装的 MIA。你在哪里可以找到这个名为 citext for postgresql 9.3 的神秘野兽？

project_test=> CREATE TABLE "customers_addresstype" (
project_test(>     "id" serial NOT NULL PRIMARY KEY,
project_test(>     "customer_id" integer NOT NULL REFERENCES "customers_customer" ("id") DEFERRABLE INITIALLY DEFERRED,
project_test(>     "display" citext NOT NULL,
project_test(>     UNIQUE ("customer_id", "display")
project_test(> )
project_test-> ;
ERROR:  type "citext" does not exist
LINE 4:     "display" citext NOT NULL,
                      ^
project_test=> CREATE EXTENSION IF NOT EXISTS citext WITH SCHEMA ext;
ERROR:  could not open extension control file "/usr/share/postgresql/9.3/extension/citext.control": No such file or directory


$ ls /usr/share/postgresql/9.3/extension

$ ls /usr/lib/postgresql/9.3/lib

我在存储库中没有看到并且locate -i citext什么也没找到。

原来答案是堆栈溢出。丹尼尔在我安装它的时候评论了它。

sudo apt-get install postgresql-contrib-9.3
