Mo Data stashed this in Big Data Technologies
When you think about open-source database management systems (DBMS), you probably think about Oracle's MySQL and its great rival/fork MariaDB. That's thinking too small. There's another great, enterprise capable DBMS, PostgreSQL, and its latest, greatest release PostgreSQL 9.3, has just arrived.
While it's not as well known as MySQL and MariaDB, PostgreSQL has its share of major users. These include Etsy, IMDB, and Creative Commons. In other words, PostgreSQL can handle millions of users and petabytes of data with the best of the enterprise DBMSs. In addition, PostgreSQL has started getting developer support from companies such as EnterpriseDBand Salesforce.com.
This latest release expands PostgreSQL's reliability, availability, and ability to integrate with other databases. According to the PostgreSQL Global Development Group, which oversees the DBMS's progress, "Users are already finding that they can build applications using version 9.3 which would not have been possible before."
