- http://www.postgresql.org/download/linux/ubuntu/
- https://wiki.postgresql.org/wiki/Apt

설치 방법

$ sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
$ wget -q https://www.postgresql.org/media/keys/ACCC4CF8.asc -O - | sudo apt-key add -

$ sudo apt-get update
$ sudo apt-get install postgresql postgresql-contrib

설치가 완료되면 progres계정이 생성된다.

$ cat /etc/passwd | grep postgres
postgres:x:108:117:PostgreSQL administrator,,,:/var/lib/postgresql:/bin/bash
$ id postgres
uid=108(postgres) gid=117(postgres) groups=117(postgres),116(ssl-cert)

접속 방법

$ sudo su - postgres
$ psql

PostgreSQL 명령행에서 접속정보 및 버전 확인 후 종료하기

postgres=# \conninfo
You are connected to database "postgres" as user "postgres" via socket in "/var/run/postgresql" at port "5432".

postgres=# select version();
                                                 version
----------------------------------------------------------------------------------------------------------
 PostgreSQL 9.5.1 on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 5.2.1-22ubuntu2) 5.2.1 20151010, 64-bit
(1 row)

postgres=# \q

그냥 우분투 기본쉘에서 버전 확인하는 방법은.....

$ sudo apt-cache show postgresql
.......
Package: postgresql
Source: postgresql-common (172.pgdg15.10+1)
Version: 9.5+172.pgdg15.10+1
.......

나,

$ postgresql설치경로/bin/postgres --version
postgres (PostgreSQL) 9.5.1

등으로 확인이 가능하다.
