PostgreSQL 10.8 Mac是全功能的自由软件数据库，很长时间以来，PostgreSQL 10.8 版本是唯一支持事务、子查询、多版本并行控制系统、数据完整性检查等特性的唯一的一种自由软件的数据库管理系统。欢迎下载体验吧！

PostgreSQL 10.8 Mac详细介绍

PostgreSQL (也叫 Postgres)是一个自由的对象-关系数据库服务器(数据库管理系统)，它在灵活的 BSD-风格许可证下发行。它提供了相对其他开放源代码数据库系统(比如 MySQL 和 Firebird)，和对专有系统比如 Oracle、Sybase、IBM 的 DB2 和 Microsoft SQL Server的一种选择。

PostgreSQL 不寻常的名字导致一些读者停下来尝试拼读它，特别是那些把SQL拼读为"sequel"的人。PostgreSQL 开发者把它拼读为 "post-gress-Q-L"。(Audio sample, 5.6k MP3)。它也经常被简略念为 "postgres"。

PostgreSQL 使用名为 PostgreSQL 的许可证，该许可证与 BSD/MIT 类似。

Ensure that automatically created child indexes are created in the same tablespace as the parent partitioned index

Fix several crashes with triggers

Fix problems with applying ON COMMIT DELETE ROWS to a partitioned temporary table

Fix how NULL values are handled when using LEFT JOIN with a parallelized hash join

Several fixes around using named or defaulted arguments in CALL statements

Fix for strict aggregate functions (i.e. aggregates that cannot accept NULL inputs) with ORDER BY columns that enforces the strictness check

Disable an optimization for updating expression indexes in order to prevent a crash

Fix a memory leak that occurred on a specific case of using a SP-GiST index

Fix for pg_verify_checksums incorrectly reporting on files that are not expected to have checksums
