Don't know.  I just thought OO was the easiest way to turn a CSV into DBF.

In the (vector) layer properties' attribute tab.  If your GDAL/OGR is capable
of adding fields the button should be enabled for shapes in editing mode.   The
delete tab will be disabled in any case for shapes as OGR cannot do that yet
(but there is a patch by Martin Dobias in GDAL's TRAC to enable field
deletion).

But given proper database permissions both buttons are enabled for postgis
layer.
