Answer 1

Postgres allows the use of any existing database on the server as a template when creating a new database.

(创建新数据库时，Postgres允许使用服务器上的任何现有数据库作为模板。)

I'm not sure whether pgAdmin gives you the option on the create database dialog but you should be able to execute the following in a query window if it doesn't:

(我不确定pgAdmin是否在创建数据库对话框中为您提供了该选项，但是如果没有，您应该能够在查询窗口中执行以下操作：)

CREATE DATABASE newdb WITH TEMPLATE originaldb OWNER dbuser;

Still, you may get:

(不过，您可能会得到：)

ERROR:  source database "originaldb" is being accessed by other users

To disconnect all other users from the database, you can use this query:

(要将所有其他用户与数据库断开连接，可以使用以下查询：)

SELECT pg_terminate_backend(pg_stat_activity.pid) FROM pg_stat_activity 
WHERE pg_stat_activity.datname = 'originaldb' AND pid <> pg_backend_pid();
