We're doing a very similar thing here for one of our legacy apps, which
luckily does not know anything about schemas, and so the search_path
trick does work.

However, for most "global" tables we have views with insert/update/
delete rules in the specific schemas, and such shield the application
from directly accessing the global data. We even need to mere local and
global data this way in some cases.

It is ugly, but it works fine and is manageable.

HTH,
Markus
