Step by Step postgres_fdw

Hello, I will create postgres_fdw and explain data transfer.

 

First of all, we create EXTENSION, the name of which we determine ourselves.

CREATE EXTENSION test;

 

We are creating a server for the machine that we will access to do the dblink task.

CREATE SERVER deneme FOREIGN DATA WRAPPER test OPTIONS (host 'xxx.xxx.xx.xx', dbname 'TEST', port '5432');

 

We are mapping users in two different environments to each other.

CREATE USER MAPPING FOR postgres SERVER cm96 OPTIONS (user 'Test' , password 'test123#');

 

We create schema on the machine where we set up dblink

CREATE SCHEMA Test;

We can move the data with the IMPORT FOREIGN command on the server we created.

IMPORT FOREIGN SCHEMA public FROM SERVER Test INTO Test;
