I may have some free time recently to work on the master-slave scan idea. I've been able to support AS-IS both SeqScan and IndexScan. Are we still interested in getting it into 8.2?
There are still some problems I am not quite sure the solution. One is the Xid assignment -- we need this to assure that master and slaves see the same snapshot. The other is the connection pool architecture: shall we let postmaster manage the slaves or let another process say slave-master to handle them? Currently I am choosing the latter.
