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.
