Online Documentation for SQL Manager for PostgreSQL
Extensions are packages, which contain multiple SQL objects.
An extension to PostgreSQL typically includes multiple SQL objects: a new data type will require new functions, new operators, and probably new index operator classes. It is convenient to collect all these objects into a single package to simplify database management.
This tool is available only for Postgres SQL Server ver. 9.1 and above.
To open the Extensions window, select the Services | Database Extensions main menu item, or right-click the database alias in the DB Explorer tree and select the Tasks | Database Extensions item from the context menu.
All available extensions are displayed in this dialog.
You can manage server extensions by using navigation bar or context menu.
