Postgresql 中文操作指南

31.11. Quick Setup #

首先在 postgresql.conf 中设置配置选项：

First set the configuration options in postgresql.conf:

wal_level = logical

其余所需设置拥有足以进行基本设置的默认值。

The other required settings have default values that are sufficient for a basic setup.

pg_hba.conf 需要进行调整以允许复制（此处的值取决于你的实际网络配置和你希望用于连接的用户）：

pg_hba.conf needs to be adjusted to allow replication (the values here depend on your actual network configuration and user you want to use for connecting):

host     all     repuser     0.0.0.0/0     md5

然后在发布者数据库上：

Then on the publisher database:

CREATE PUBLICATION mypub FOR TABLE users, departments;

在订阅者数据库上：

And on the subscriber database:

CREATE SUBSCRIPTION mysub CONNECTION 'dbname=foo host=bar user=repuser' PUBLICATION mypub;

以上内容将开始复制过程，该过程将同步表 users 和 departments 的初始表格内容，然后开始复制对此类表格的增量更改。

The above will start the replication process, which synchronizes the initial table contents of the tables users and departments and then starts replicating incremental changes to those tables.
