Who is using Postgres?

[nelsonic]

NOT that you/we should ever make a decision based on someone else using something, but as humans we naturally give "credibility" to something based on "social proof".

Mostly people (CIOs/CTOs) don't want to feel like they're making the "wrong" decision...
So having a list of "successful companies/organisations use XYZ Tech..." is useful in "high level" discussions...

List

• Instagram
• Skype
• Uber
• Spotify
• Netflix
• Reddit (still the most popular "social discussion" site)
• Citrix
• Atlassian (JIRA etc.)
• Disqus (the biggest commenting system on the internet!)
• Hipmunk (fastest growing travel search engine)
• Etsy (community driven e-commerce)
• Heroku
• DuckDuckGo (search engine)
• Twitch (the most popular online streaming platform)
• comScore, Inc.
• Zalando (Europe's answer to Zappos/Amazon)
• The US State Department
• EnterpriseDB
• IMDB.com (biggest movie/film/TV actor database with the most reviews and box office data)
• BASF (the worlds largest chemical company_)

anyone "concerned" that PostgreSQL does not "scale" look at CitusDB: https://www.citusdata.com

I think its worth noting too that many "big data" or "cloud scale" databases (eg AWS Redshift, Netezza, Greenplum, etc) are based on PostgreSQL, and as such many more companies rely on a PostgreSQL-based solution as well.

PostgreSQL is a database with great features easy to setup and useable on Heroku and some other Cloud Platform (Ms Azure ). Personally used with Rail 5 for a backend application and I must to say "wonderful".
