Disclaimer: I have not tried this.

I believe you need to implement a custom database back end. There are a few examples on the web that shows how to implement a database back end with connection pooling.

Using a connection pool would probably be a good solution for you case, as the network connections are kept open when connections are returned to the pool.

• This post accomplishes this by patching Django (one of the comments points out that it is better to implement a custom back end outside of the core django code)
• This post is an implementation of a custom db back end

Both posts use MySQL - perhaps you are able to use similar techniques with Postgresql.

Edit:

• The Django Book mentions Postgresql connection pooling, using pgpool (tutorial).
• Someone posted a patch for the psycopg2 backend that implements connection pooling. I suggest creating a copy of the existing back end in your own project and patching that one.
