AWS RDS : PostgreSQL 1
PostgreSQL is a general purpose and object-relational database management system, the most advanced open source database system (see http://www.postgresql.org/).
Compared to other RDBMSs, PostgreSQL differs itself with its support for highly required and integral object-oriented and/or relational database functionality, such as the complete support for reliable transactions, i.e. Atomicity, Consistency, Isolation, Durability (ACID).
Due to the powerful underlying technology, Postgres is extremely capable of handling many tasks very efficiently. Support for concurrency is achieved without read locks thanks to the implementation of Multiversion Concurrency Control (MVCC), which also ensures the ACID compliance.
PostgreSQL is highly programmable, and therefore extendible, with custom procedures that are called "stored procedures". These functions can be created to simplify the execution of repeated, complex and often required database operations.
In this tutorial, we'll see how we can create a Postgres DB vis RDS.
RDS provides options for DBs we can choose from:
We need to modify the Security Group allowing None from All:
$ nc -vz test-postgres-db-instance.ca1jql6qyqdz.us-west-1.rds.amazonaws.com 5432
found 0 associations
found 1 connections:
1: flags=82<CONNECTED,PREFERRED>
outif utun0
src 172.27.235.208 port 60415
dst 172.31.5.252 port 5432
rank info not available
TCP aux info available
Connection to test-postgres-db-instance.ca1jql6qyqdz.us-west-1.rds.amazonaws.com port 5432 [tcp/postgresql] succeeded!
If we only want to connect to a PostgreSQL server, we don't have to install the whole PostgreSQL package, but install the PostgreSQL client instead:
$ sudo apt-get install postgresql-client $ psql --version psql (PostgreSQL) 9.3.6 $ psql --host=test-postgres-db-instance.ca1jql6qyqdz.us-west-1.rds.amazonaws.com --port=5432 --username=testdbuser --password --dbname=NameOfMyDB Password for user testdbuser: psql (9.3.6) SSL connection (cipher: DHE-RSA-AES256-SHA, bits: 256) Type "help" for help. NameOfMyDB=>
pgAdmin III is a handy GUI for PostgreSQL, it is essential to beginners. To install it, type at the command line:
$ sudo apt-get install pgadmin3
To get an idea of what PostgreSQL can do, we may start by firing up a graphical client. To launch the pgAdmin application on client computer, in a terminal type :
$ pgadmin3
Then, we will be presented with the pgAdmin III interface. Click on the "Add a connection to a server" button (top left):
In the New Server Registration dialog box, enter the following info:
- DB name : NameOfMyDB
- Host (DB instance endpoint) : test-postgres-db-instance.ca1jql6qyqdz.us-west-1.rds.amazonaws.com
- Username : testdbuser
- Password :
Click OK.
In the Object browser, expand the Server Groups. Select the Server (the DB instance) we created, and then select the database name:
(Note on "rdsadmin") - This is Amazon's own user that is used by Amazon to perform updates, run backups and do other maintenance tasks.
