用户管理 — Postgres Guide

http://pgguide.lxneng.com/setup/users.html

连接到你的数据库中开始工作, 当然首先要做的应该为自己创建一个帐户. 这个数据库上拥有所有的权限. 这些权限种类是: SELECT, INSERT, UPDATE, DELETE, RULE, REFERENCES, TRIGGER, CREATE, TEMPORARY, EXECUTE, and USAGE. Beginning Databases with PostgreSQL. SQL and Relational Theory. Enter search terms or a module, class or function name.

条件约束(Conditional Constraints) — Postgres Guide

http://pgguide.lxneng.com/performance/conditional.html

有时候你可能想要对数据进行约束, 但只希望他们在某些情况下存在. 让我们来看个例子, 你不想物理的删除用户，而且想做逻辑删除, 如果用户几个月后又回来了那么通过局部索引(Partial Indexes). Previous: 执行计划 (Execution Plan). Beginning Databases with PostgreSQL. SQL and Relational Theory. Enter search terms or a module, class or function name.

日期和时间 — Postgres Guide

http://pgguide.lxneng.com/tips/dates.html

一个常见的活动与任何数据库或者编程语言都要同时间和日期打交道. Postgres有几个时间和日期数据类型, 可以很好的简化你的工作. Date - 日期 (2012-04-25). Time - 时间 (13:00:00.00). Timestamp - 日期和时间 (2012-04-25 13:00:00.00). Time with Timezone - 时间加时区 (13:00:00.00 PST). Timestamp with Timezone (2012-04-25 13:00:00.00 PST). Interval - 时间段 (4 days). 很幸运的Postgres可以接受多种格式的时间和日期, 官方文档中很详细的描述了各种格式所以我们这里将跳过它们: Date input format. 和 Timezone input format. 如下面的例子, 时间段(interval)是一个用来查询两个时间范围的实用工具, 类似于上面的例子中，你可能想要查询过去24小时内注册的用户数:.
