Why would I want to use PostgreSQL?
PostgreSQL for Solaris is the right choice for proprietary database users who want to lower their TCO but keep their advanced capabilities, or for open source database users who want lower costs but also need enterprise-class features and reliability. PostgreSQL for Solaris is an excellent fit for any application that requires a scalable, heavy-duty SQL database server, such as financial applications, high-traffic websites, and data warehousing.
