DBBalancer 0.3.0: Connection pòoling and load balancing for PostgreSQL

Hello everybody.

I've just released the 0.3.0 version of DBBalancer.
DBBalancer is a program that has several functions:

- Provides connection pooling.
- Provides load balancing over replicated databases and
- Provides write replication. This feature is just experimental, needing
still quite a lot of testing.

I'd like you to share your feelings about it with me. It would be usefult to
talk about if this is useful, if you consider the concept valid, and anything
you want.

You can answer in this list (I read it almost every day) or, if this is not
appropiate, in the specific DBBalancer Sourceforce mailing list at
dbbalancer-users(at)lists(dot)sourceforge(dot)net(dot)

The project source is at http://www.sourceforge.net/projects/dbbalancer

These are the changes introduced in version 0.3.0:

0.3.0:
- New config file format, no longer XML.
- Xerces requirement removed. Hope this makes compiling easier.
- Documentation updated.
- In "write replication" mode, start a transaction for each connection.
Rollback if a error is detected in any of the backends. This is configurable
- Write replication enhancements.

WARNING: Though some features are believed to work more safely than others,
none of them has passed extensive testings. So please don't use it with
valuable data.
