Prepared statements?

Hello.

I'm wondering if psycopg2 has an API for server-side
prepared statements.  And if so, how to use it efficiently?
And if not... well what are the road blocks? ;)

The other question is about execute() command, so far
I have seen two syntaxes:

  execute("SELECT foo FROM bar WHERE baz=%d" % intval)
  execute("SELECT foo FROM bar WHERE baz=%s", (intval,))

...seems like the latter is more efficient (and seems it doesn't
like "%d").  Am I correct?  Or maybe there are other syntaxes
that are even better?

   Regards,
       Dawid
