I do not know if it is implemented in Lazarus connections, but if you
put "KeepConnected" to false in the connection control, when no
control needs the connection it should be closed. So if you close all
forms that uses queries the connection should be closed, but keep in
mind that if you leave a query, in the module, open the connection
will not be closed.

Best regards,
