Two questions from the boss (SQL:2003 && scalability)

Guys,

My boss has been keeping himself busy reading MySQL marketing pubs,
and came at me with a few questions this morning regarding PostgreSQL
features (we're currently moving to PostgreSQL).

While I don't think either are really that important for our
situation, he wanted to know specifically whether PostgreSQL supported
SQL:2003, and what sort of capabilities PostgreSQL has to scale across
multiple CPUs and hosts (multithreading, load balancing, etc).

I appreciate any input you can provide.

Thanks,
JB
