The new graphical query editor in Grafana v5.3 for PostgreSQL offers a visual interface that makes it easier for users to explore time-series data, improving discoverability of data stored in PostgreSQL. The query editor combines the usability of the interface with the power of full SQL, allowing users to generate dynamic dashboards and visualizations in Grafana without needing deep knowledge of database schema or SQL language. This new feature is a contribution made by TimescaleDB engineers to the open-source Grafana community, enhancing the first-class integration between TimescaleDB and Grafana for PostgreSQL. The query editor also includes features such as drop-down menus and macros that cater to time-series specific functionalities, making it easier for users to work with time-series data in PostgreSQL.
