+=head2 should_quote_value
+
+This method is called by L</_prep_for_execute> for every column in
+order to determine if its value should be quoted or not. The arguments
+are the current column data type and the actual bind value. The return
+value is interpreted as: true - do quote, false - do not quote. You should
+override this in you Storage::DBI::<database> subclass, if your RDBMS
+does not like quotes around certain datatypes (e.g. Sybase and integer
+columns). The default method always returns true (do quote).
+
+ WARNING!!!                     
+
+ Always validate that the bind-value is valid for the current datatype.
+ Otherwise you may very well open the door to SQL injection attacks.
