Sounds somewhat evil, I know, but I was wondering if it was even
remotely possible with the current design?
The reason: we are contemplating using pg_standy to create a
warm-standby. It would be a bonus if we would run read-only queries
against this DB to take some of the load off or production servers.
We currently use slony to provide warm-standby *and* read-only access,
but pg_standby is a great deal more appealing...especially if there was
some way to do read-only access at the same time.
FWIW, the data would not even need to be completely consistent ... the
kinds of things we are looking at offloading are large summary-type
sequential scans of big tables.
