Wiki: The pgAdmin package is a free and open-source graphical user interface(GUI) administration tool for PostgreSQL, which is supported on many computer platforms. It is designed to handle a range of workloads, from single machines to data warehouses or Web services with many concurrent users. Wiki: PostgreSQL, also known as Postgres, is a free and open-source relational database management system(RDBMS) emphasizing extensibility and technical standards compliance.

The UI is much more attractive, making use of control groupings and expandable regions to make things more readable.We also spend time thinking about how to make it faster to use pgAdmin, by minimising the need to switch between dialogues, using searchable combo boxes and more.Gone are the list controls with Add/Remove buttons, replaced with what we call sub-node grid controls that will allow in-grid editing of key values, with more detail available when needed in expandable rows. We've spent time redesigning some of the UI paradigms in pgAdmin 3.The user interface is more flexible than ever, allowing tabs to be docked and re-arranged in more ways than previously.For now though, updating is allowed when pgAdmin knows the data source is a single table with a primary key. Over coming releases we'll be improving the functionality further to allow in-grid updates to be made to results from arbitrary queries (where a query is determined to be updateable). The Query Tool and Edit Grid have been merged into a single tool.We haven't (yet) reimplemented some of the tools that didn't work so well in pgAdmin 3, such as the graphical query builder or database designer (which was always disabled entirely by default).We haven't re-implemented support for some object types that no one really used in the tool before - for example, operator classes and families.Support for unsupported database versions has been dropped.Whilst the core functionality of pgAdmin 4 remains similar to pgAdmin 3, there are a number of changes we've made: A small runtime application allows it to be run as a desktop application - this is a Qt executable that incorporates a Python interpreter and web browser along with the main application in a single package that can be installed on a developer laptop as with previous versions of pgAdmin. Written in Python using the Flask framework for the backend, and Javascript/ jQuery/ Backbone for the frontend, it can easily be deployed as a WSGI application for multiple users in practically any network environment. This new application is designed for operation on both the desktop and a webserver. Right now, we're approaching alpha-readiness which we expect to be at within a few weeks. Work on the project began slowly, almost two years ago, however the team at EnterpriseDB have ramped up the development pace over the last few months. pgAdmin 4 is a complete rewrite of pgAdmin (the fourth, as you may guess), the previous version having reached the end of it's maintainable life after 14 years of development. As you may know, many of us from the pgAdmin team have been hard at work on pgAdmin 4 for some time now.
