In Database Tour, there is a possibility to work with the list of database sessions (open database connections) in the currently opened database.

The corresponding user interface is available by choosing Tools | Sessions... menu.

Here, you can view the list of sessions/connections and their attributes like username, connection time etc. It is possible to order the list by one or several columns, filter it, as well as killing selected session (if your database user has permissions to do it). For PostgreSQL database, you can cancel the active query from selected connection.

Note: This interface is currently supported only for Oracle, SQL Server, PostgreSQL, MySQL, and Amazon Redshift databases.
