It is part of adbapi in Twisted 2.0 (see cp_reconnect arg to the 
DatabasePool constructor). However, it will only reconnect after 
failing a query. It will never retry a query (that could be unsafe to 
do), but will re-establish the database connection after that query 
fails. Thus, subsequent queries will succeed.

If you know some way to tell for sure that it there is no possibility 
that the query has been executed, you could submit a patch for adbapi 
that it will retry the query in those circumstances.
