4. 현재 데이터베이스 목록 보기

postgres=# \l
                                  List of databases
   Name    |  Owner   | Encoding |   Collate   |    Ctype    |   Access privileges   
-----------+----------+----------+-------------+-------------+-----------------------
 postgres  | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | 
 template0 | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =c/postgres          +
           |          |          |             |             | postgres=CTc/postgres
 template1 | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =c/postgres          +
           |          |          |             |             | postgres=CTc/postgres
(3 rows)

5. 기본 데이터베이스에 pgagent 확장 설치

postgres=# create extension pgagent;
CREATE EXTENSION

설치 확장 성공
서비스 시작, 종료, 전원 켜기 시작 설정

    
[root@localhost ~]# systemctl start pgagent_11
    
[root@localhost ~]# systemctl stop pgagent_11
        
[root@localhost ~]# systemctl status pgagent_11
      
[root@localhost ~]# systemctl enable pgagent_11
        
[root@localhost ~]# systemctl disable pgagent_11

6. 지정된 데이터베이스에 확장 설치
(1) 테스트 데이터베이스를 만들고 목록을 보기

postgres=# create database pgtest;
CREATE DATABASE
postgres=# \l
                                  List of databases
   Name    |  Owner   | Encoding |   Collate   |    Ctype    |   Access privileges   
-----------+----------+----------+-------------+-------------+-----------------------
 pgtest    | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | 
 postgres  | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | 
 template0 | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =c/postgres          +
           |          |          |             |             | postgres=CTc/postgres
 template1 | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =c/postgres          +
           |          |          |             |             | postgres=CTc/postgres
(4 rows)

(2) 데이터베이스 전환

postgres=# \c pgtest
You are now connected to database "pgtest" as user "postgres".
pgtest=#

(3) 확장postgis 설치

pgtest=# create extension "uuid-ossp";
CREATE EXTENSION

(4) 설치 확장 uid-ossp

pgtest=# create extension postgis;
CREATE EXTENSION

(5) 확장 ltree 설치

pgtest=# create extension "ltree";
CREATE EXTENSION

(6) 확장timetravel 설치

pgtest=# create extension "timetravel";
CREATE EXTENSION

추가 확장: 생략.
(7) 현재 설치된 확장 보기

pgtest=# \dx
                                      List of installed extensions
    Name    | Version |   Schema   |                             Description

 timetravel | 1.0     | public     | functions for implementing time travel
 uuid-ossp  | 1.1     | public     | generate universally unique identifiers (UUIDs)
(5 rows)

(8) Extension 확장 제거, 결과 보기

pgtest=# drop extension timetravel;
DROP EXTENSION
pgtest=# \dx
                                      List of installed extensions
