With Gartner predicting that 70% of new applications soon will be deployed
on an open-source relational database, purveyors of proprietary DBMSes
surely long for the golden lock-in age of yore. Said trend is in no small
part due to the surging PostgreSQL, which recently stepped up to a new version
9.5. Highlights of this release, reported the PostgreSQL Global Development
Group, include the addition of UPSERT capability, Row Level Security and
multiple Big Data features, all of which the Group hopes will broaden the
user base for the database. The Group added that version 9.5 marks a
turning point for use of Postgres with data-driven applications of
engagement and high-speed, high-volume mobile, Web and digital apps. Other
specific features are performance boosters for today's more powerful
"big iron" servers, analytics and productivity enhancements to
speed complex query capabilities on extreme data volumes, and a foundation
for horizontal scalability across multiple servers for importing entire
tables from external databases.
