Installing EDB Postgres Advanced Server on Ubuntu 20.04 x86_64 v14

Prerequisites

Before you begin the installation process:

• Set up the EDB repository.

  Setting up the repository is a one-time task. If you have already set up your repository, you don't need to perform this step.

  To determine if your repository exists, enter:

  apt-cache search enterprisedb

  If no output is generated, the repository isn't installed.

  To set up the EDB repository:

  1. Go to EDB repositories.

  2. Select the button that provides access to the EDB repository.

  3. Select the platform and software that you want to download.

  4. Follow the instructions for setting up the EDB repository.

Install the package

sudo apt-get -y install edb-as<xx>-server

Where <xx> is the version of the EDB Postgres Advanced Server you're installing. For example, if you're installing version 14, the package name is edb-as14-server.

To install an individual component:

sudo apt-get -y install <package_name>

Where package_name can be any of the available packages from the available package list.

Initial configuration

This section steps you through getting started with your cluster including logging in, ensuring the installation was successful, connecting to your cluster, and creating the user password.

To work in your cluster, log in as the enterprisedb user. Connect to the database server using the psql command-line client. Alternatively, you can use a client of your choice with the appropriate connection string.

sudo su - enterprisedb

psql edb

The server runs with the peer or ident permission by default. You can change the authentication method by modifying the pg_hba.conf file.

Before changing the authentication method, assign a password to the database superuser, enterprisedb. For more information on changing the authentication, see Modifying the pg_hba.conf file.

ALTER ROLE enterprisedb IDENTIFIED BY password;

Experiment

Now you're ready to create and connect to a database, create a table, insert data in a table, and view the data from the table.

First, use psql to create a database named hr to hold human resource information.

# running in psql
CREATE DATABASE hr;

CREATE DATABASE

Connect to the hr database inside psql:

\c hr

psql (14.0.0, server 14.0.0)
You are now connected to database "hr" as user "enterprisedb".

Create columns to hold department numbers, unique department names, and locations:

CREATE TABLE public.dept (deptno numeric(2) NOT NULL CONSTRAINT dept_pk
PRIMARY KEY, dname varchar(14) CONSTRAINT dept_dname_uq UNIQUE, loc
varchar(13));

CREATE TABLE

Insert values into the dept table:

INSERT INTO dept VALUES (10,'ACCOUNTING','NEW YORK');

INSERT 0 1

INSERT into dept VALUES (20,'RESEARCH','DALLAS');

INSERT 0 1

View the table data by selecting the values from the table:

SELECT * FROM dept;

deptno  |   dname    |   loc
--------+------------+----------
10      | ACCOUNTING | NEW YORK
20      | RESEARCH   | DALLAS
(2 rows)
