#2 Multiply db connections

[Frédéric RUAUDEL]

You can make many sqlb connections to the same
database. To do this, you just have to set 2 different
group name in the configuration.

example :

<pg@dbtest1>
...
DB_NAME=foobar
</pg@dbtest1>

<pg@dbtest2>
...
DB_NAME=foobar
</pg@dbtest2>

This kind of config allow to send slow queries that are
not send very often to one of the connection and other
quick queries to the other.
