PostgreSQL Database Server

PostgreSQL Database Server

PostgreSQL is an open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads. PostgreSQL comes with many features aimed to help developers build applications, administrators to protect data integrity and build fault-tolerant environments, and help you manage your data no matter how big or small the dataset. In addition to being free and open source, PostgreSQL is highly extensible. For example, you can define your own data types, build out custom functions, even write code from different programming languages without recompiling your database.

Features

  • AAMI built with the latest, stable version of PostgreSQL.
  • AMI compatible for spinning up PostgreSQL database nodes with the service up and running.
  • AMI is built on a patched operating system and the node created from this is ready to be deployed in production.

How It Works

  • When an EC2 node spun up from this AMI, the PostgreSQL service is up and running.
  • SSH into the newly spun up node if you need to perform any additional configuration. The database port 5432 is open and you could connect to the database instance remotely also.

Configuration

  • When an EC2 node spun up from this AMI, the database service would be available on port 5432.
  • The database service can be managed using standard steps:
$ sudo systemctl \[start|stop|status\] POSTGRESQL.service  

where the POSTGRESQL name is specific to the operating system as follows:

  • Ubuntu: postgresql@13-main
  • Debian: postgresql@13-main
  • Red Hat Enterprise Linux 7: postgresql-13
  • Red Hat Enterprise Linux 8: postgresql
