Yep.

In your ogr2ogr query string query try 
"select buffer(area, nn.nn) as geom from table where...;"

PostGIS will buffer it before sending it to GDAL for export to shapefile.

Or if you are repeatedly doing this, create a view in PostGIS with the buffer, & select this with GDAL, whichever suits....
