Thanks for the suggestion. As I noted we are already using pl/proxy and it works well, although we are soaking up a lot of connections with it. >From my reading of the postgres_fdw docs it is much more featureful than pl/proxy but it is likely to have the same connection characteristics. The main issues we're trying to solve is standardising data access through (I think) materialisation and centralisation. Rory
