Subject: [SQL] How to duplicate postgres 9.4 database

Hi All

I want to duplicate the existing database , after reading documentation I used below command which just created
database,but did not create data 
CREATE DATABASE standby TEMPLATE template0;


my database is 35gb so dump and psql will take longer hours

is there an fastest way to copy database on same server , so that I can just modify pointing to the database and
connectto the stanby one to do any testing ?

As a TEMPLATE you should use the db that you want to copy, let's call it "source_db":

CREATE DATABASE standby TEMPLATE source_db;

Be aware, that when this statement runs there should be no user connections to source_db.
