If you already have an IActionDelegate you can use IAction#setEnabled(*)
to disable the database button, no?
The IAction will only be updated on selection change, though.
The other way (supported in 3.3.x) is to write a command/handler and
then use menu contributions to place the command in the toolbar. The
handler can change its enabled state and fire a HandlerEvent, and the
tool item will be updated.
