The latest release of the PostgreSQL open-source object-relational database management system (ORDBMS) comes with native support for the JSON data format.
Native JSON support speeds up the PostgreSQL data process by eliminating the tedious storage and retrieval required to restructure each JSON file.
Other new features in PostgreSQL 9.4 include:
• Logical decoding to stream out database changes in a customizable format
• Dynamic registering of the start and termination of background workers
• Materialized views refreshed without blocking reads
• SQL-level ALTER SYSTEM command to edit the postgresql.conf configuration file
More details can be found in the PostgreSQL 9.4 release notes.
