Correct. Legacy apps will keep working as long as you don't reference 
non-default schemas explicitly. So per-schema apps are going to work, 
while cross-schema ones won't (without polluting everything with synonyms).

And I have serious doubts we need them. PGSQL has schemas and doesn't 
have synonyms. I'd prefer us going the same route.

Can you name some RDBMS that support nested schemas? I tend to say "over 
my dead body" to this.
