How to Create PostgreSQL Test Data, by Alex Thompson Generating Fake Data Using SQL, by Vinicius Negrisolo But in the spirit of open source, let’s take a look at the tools available for creating mock data in-house.įor specific, step-by-step instructions on how to create mock data using PostgreSQL, here are two great resources: In fact, Postgres was the first database type we supported in the early days of Tonic for this very reason. Given its popularity, it naturally follows that there’s an ever-growing need for protecting and synthesizing data stored in Postgres. Postgres is no stranger to scale: it's been tried and tested in workloads that have reached hundreds of thousand TPS in heavy I/O workloads.Ĭompanies across industries, including the likes of Northrop Grumman, NASA, and Revolt, use PostgreSQL to store sensitive data like financial transactions, classified information, PII, PHI, and confidential client data. Some of the largest databases in the world are hosted in Postgres, including a Yahoo! database that claimed it broke a record when it reached 2 petabytes back in 2008.

You'd be surprised to learn that Postgres supports a wide spectrum of format's that are leveraged by developers, including XML, spatial coordinates, key/value pairs, JSON, and more.

In Postgres, developers can work with NoSQL code and store JSON files, which means more storage options and flexibility.

it has a wide range of features that enable the management of datasets large or small.

it has an active community without a single controlling entity.

The main reasons companies choose Postgres are: With 30 years of continual improvement and a rapidly growing user base, it’s a fierce contender in the SQL database sphere. PostgreSQL is an open-source object-relational database out of the University of California at Berkeley that has origins as early as 1986. There are also many challenges involved in doing this in-house. TL DR: There are many resources available for creating synthetic data in PostgreSQL.
