Hi John,
Short answer: you can do cross-schema queries, you can't (easily) do
cross database queries.
Check out this:
http://www.postgresql.org/docs/7.4/static/ddl.html
, the schema section:
http://www.postgresql.org/docs/7.4/static/ddl-schemas.html
I'm not sure when schemas were introduced, but I suppose you want to use
the latest postgres version.
Cheers,
Csaba.
