Overview

Amazon RDS is a relational database service software designed to help users set up, operate and scale databases such as Amazon Aurora, MySQL, MariaDB, Oracle, Microsoft SQL Server, and PostgreSQL in the cloud. Users can manage routine database tasks like patching and provisioning, and more.

PostgreSQL is an open-source relational database management system (RDBMS), which helps businesses store, manage, and scale data workloads, from single machines to data warehouses with multiple concurrent users.

Pros

“Configuration and out-of-the-box setups allowed for the rapid testing and then replication and rollout across the business.”

Richard R.

IT Support Analyst

“same applies for reducing storage of the database, you can increase the storage but cannot lower the storage”

Prateek G.

Senior Software Engineer

“Being able to increase and decrease the size of the database on demand is just great.”

Esteban O.

CTO

Pros

“Postgres implements catalog internally, so it stores differently from other RDBMS(s).”

Shaunak P.

Senior Data Engineer

“PostgresSQL is very famous among the data engineering fraternity due to its high resilience and throughput.”

Shaunak P.

Senior Data Engineer

“PgAdmin is best tool to manage the DB with intuitive UI.”

Shaunak P.

Senior Data Engineer

Cons

“Overall I couldn't imagine running a database on production without RDS, and it requires very little thought when running outside of the upgrade windows.”

Samuel H.

Senior DevOps Engineer

“We used to suffer by having to expand or decrease the size of the database a lot of times during the month.”

Esteban O.

CTO

“It is costly for high performance workloads and complex while setting up in multi AZ deployments.”

Shashank A.

Intern

Cons

“The only problem I faced with Postgres SQL was that API people need column comments, and for a table with huge number of columns like 250-300 fields, it is very hard to update column via SQL query. And there is no provision in Postgres to tag comment to a column with DDL statement.”

Shaunak P.

Senior Data Engineer

“The diagram feature isn't as customizable as I would prefer.”

Leslie H.

Student

“One thing that i dislike from PostgreSQL is it's hard to setup and install PostgreSQL at the beginning.”
