This table cannot be round tripped via the 

CREATE TABLE GOOD (
  sometext text NOT NULL,
  UNIQUE KEY sometext2 ( sometext(150))
) 

dbicdump -o dump_directory=./lib  -o
components='["InflateColumn::DateTime"]' DFL::Schema::TEST
"dbi:mysql:database=$1:host=dbslave2" UID PWD '{ overwrite_modifications
=> 1, quote_char => "`" }'

Produces :

__PACKAGE__->add_unique_constraint("sometext2", [ "sometext"]);

This produces bad sql when deployed:


my $schema = Test::Schema::TEST->connect("dbi:mysql:dbname=${db}",
$user, $pass);
    $schema->create_ddl_dir(['MySQL', 'SQLite', 'PostgreSQL'],
			    '0.1',
			    './sql/'
	);

    $schema->deploy({ add_drop_table => 1});
