+=head2 connect_info
-Uses C<prepare> instead of the usual C<prepare_cached>, seeing as we can't cache very effectively without bind variables.
+We can't cache very effectively without bind variables, so force the C<disable_sth_caching> setting to be turned on when the connect info is set.

+=head2 should_quote_data_type
+
+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 sole
+argument is the current column data type, and 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+interpreted as: true - do quote, false - do not quote.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).
