Ticket #1874 - Firebird adapter
 r3107@asus:  jeremy | 2005-11-16 00:06:14 -0800
 quote column aliases
 r3108@asus:  jeremy | 2005-11-16 00:08:12 -0800
 quote columns in construct_conditions_from_arguments.  update sequence_name docs.  introduce prefetched primary keys.

 double-quote rather than single-quote sqlite columns
 r3110@asus:  jeremy | 2005-11-16 00:09:56 -0800
 quote column names and use attribute_condition in validates_uniqueness_of
 r3111@asus:  jeremy | 2005-11-16 00:12:24 -0800
 Use QUOTED_TYPE constant in tests
 r3112@asus:  jeremy | 2005-11-16 00:13:28 -0800
 restrict test_inserts_with_pre_and_suffix to those adapters which support migrations
 r3113@asus:  jeremy | 2005-11-16 00:14:09 -0800
 Use QUOTED_TYPE constant in tests
 r3114@asus:  jeremy | 2005-11-16 00:14:30 -0800
