* @short_description: Virtual connection which bind together connections
* @title: GdaVconnectionHub
* @stability: Stable
* @see_also:
*
* The #GdaVconnectionHub object "binds" together the tables from other (opened) connections to make it possible to run
* SQL queries on data from several connections at once.
*
* A #GdaVconnectionHub connection can bind several other connections, each separated in its own namespace (which is specified
* when adding a connection using gda_vconnection_hub_add()).
*
* For example if a connection A has two tables 'table_1' and 'table_2', then after gda_vconnection_hub_add() has been called
* with A as connection argument and with a "c1" namespace, then in the corresponding #GdaVconnectionHub connection, table
* 'table_1' must be referred to as 'c1.table_1' and 'table_2' must be referred to as 'c1.table_2'.
