Currently we can create a read only transaction which at this point pgpool through some machinations which are less than favourable IMO can connect to a secondary. This even works with the JDBC driver which has setReadOnly facility on connections. However it would be far better to have a startup parameter which indicated that we wanted to connect to a read only database. At that point pools could redirect to a secondary. Given the proliferation of cloud based implementations I can see this being a useful feature. Regards, Dave Cramer
