asterisk users - Feb 2011 - res_pgsql re-connect on db failure?

We are using PostgreSQL real-time connector (res_config_pgsql) with Asterisk
1.6.2.15.

From time to time, we need to reset our PostgreSQL server, causing all active DB
connections to close. While other packages in our system re-connect gracefully
when this happens, Asterisk appears to not bother trying. It instead goes into
an endless loop complaining that the connection has closed.

Question -- is there any option I might be missing, to tell Asterisk to try
re-connecting to PostgreSQL if the existing connection fails?

Thank you,

Bryan
