A patch it is (enclosed).

If this documentation is customaty, this should be mentioned in the
"Contribute" page of Worg (which, IMHO, should be pointed to by the 
"Feedback" section of the manual).

 The new paramater ~:dbconnection~ allows to specify a connection name
 in a SQL block header: this name is used to look up connection
 parameters in ~sql-connection-alist~.
+
+*** New ~LATEX_ATTR~ ~:scale~ supported by the built-in LaTeX exporters
+
+The builtin ~org-latex-export*~ exporters now accept and use a
+~:scale~ attribute, which scales an image by a given factor.
+
+This attribute is wrapped adound the ~scale=~ parameter of LaTeX's
+~\\includegraphics~ (bitmap images) or a ~TiKZ~'s
+~\\scalebox~. Therefore, its value should be some string palatable to
+LaTeX as a positive float Its default value is an empty string
+(i.e. disabled).
+
+This attribute *overrides* the ~:width~ and ~:height~ attributes ;
+therefore, while it can be given a default value, this should be done
+only under exceptional circumstances.
+

+#+name: Beastie
+#+caption: I think I saw this curious horse already, but where ?
+#+LATEX_ATTR: :scale 2
