Postgres 9.3 feature highlight - \watch in psql

2013-05-02 05:01:04 +0000

psql is the native client of PostgreSQL widely used by application developers and database administrators on a daily-basis for common operations when interacting with a PostgreSQL server. With a full set of integrated functionalities, it is among the most popular (if not the number one) client applications in the Postgres community. If you are a Postgres nerd (highly possible if you are reading this page), you know that the feeling of discovering a new functionality in psql is close to the excitement you can have when opening a christmas present as you know that such a feature went though the strict community review process. The upcoming release 9.3 of Postgres is not an exception and brings a new useful command called \watch. This feature has been introduced by this commit:

Postgres 9.3 feature highlight - JSON data generation

Postgres 9.2 has introduced JSON as a server data type. At this point, the data was simply stored on server side with integrated wrappers checking that data had a correct JSON format. It was a good first step in order to store directly JSON data on server side but core features in 9.2 have its limitations in terms of JSON data manipulation and transformation.
