Thanks Marko,
So is this "single-database, schemas mimic nodes" setup possible to
achieve at all?
My intention was:
#1. client calls func()
#2. plproxy calls func() on part0. part0 is defined as 'user=part0' so
it directs to part0.func() thanks to current_schema setting.
#3. plproxy calls func() on part1 (paralell to #2). logic same as #2.
#4. plproxy combines result and sends it to client.
Is schema a part of function signature?
regards,
Filip
