Success stories

PostgreSQL is used in many application domains including communication, medical, geographical, and e-commerce applications. Many companies provide consultation as well as commercial services, such as migrating proprietary RDBMS to PostgreSQL in order to cut off the licensing costs. These companies often influence and enhance PostgreSQL by developing and submitting new features. The following are a few companies that have used PostgreSQL:

• Skype uses PostgreSQL to store user chats and activities. Skype has also affected PostgreSQL by developing many tools called SkyTools.
• Instagram is a social networking service that enables its user to share pictures and photos. 
• The American Chemical Society (ACS) uses PostgreSQL to store more than one terabyte of data for the journal archive.

In addition to the companies mentioned in the preceding list, PostgreSQL is used by HP, VMware, and Heroku. PostgreSQL is used by many scientific communities and organizations, such as NASA, due to its extensibility and rich data types.
