ANNOUNCE: Alzabo 0.44

Alzabo is a program and a module suite, with two core functions. Its first
use is as a data modelling tool. Through either a schema creation
interface or a perl program, you can create a set of schema, table,
column, etc.  objects to represent your data model. Alzabo is also capable
of reverse engineering your data model from an existing system.

Its second function is as an RDBMS to object mapping system. Once you have
created a schema, you can use the Alzabo::Runtime::Table and
Alzabo::Runtime::Row classes to access its data. These classes offer a
high level interface to common operations such as SQL SELECT, INSERT,
DELETE, and UPDATE commands.


This is mostly a bugfix release with one nice new feature in the schema
creator.

Changes:

0.44

Bug fixes:

- Bug fix in Alzabo::Runtime::Table->set_prefetch.  Reported by Bob
Gustafson.

- Don't try to make directories when running Makefile.PL.  Save it for
later after user does 'make install'.

- Fix handling of geometric types in Postgres (they were all being
rejected as invalid).

- Drop columns from a table before adding new ones.  Sometimes this
makes a difference.  For example, if you are using MySQL and drop an
existing AUTO_INCREMENT column and add a new one that is also
AUTO_INCREMENT.

- Only allow one sequenced column per table when using MySQL.

- Doc fixes.  Thanks to Ron Savage for pointing me towards some of
these.

- Fix a bug with the schema creator.  If you attempted to make a
change to a column with an extended type and you did not change the
type, an error occurred.

Enhancements:

- Schema creator now shows you a list of possible column types instead
of having you type it in.  However, for complex types like MySQL's
ENUM or Postgres' POLYGON there is a text box to type it in.
