Or glib-ish:

  blankrow = g_new ((gchar *), vpsql->cols);

But remember to use g_free() to free the memory g_new() allocates
for you.

or:

  for (ctr = 0; ctr < vpsql->cols; ctr++)
    blankrow[ctr] = "";

since it shouldn't hurt to use the same constant empty string 
everywhere. In that case you should of course not try to free 
it later.
