By and large, the BSD license doesn't put *any* requirements on you.
We'd get unhappy if you tried to claim you owned Postgres, but short
of that you can include it in your product without any problem.

Sufficient, certainly; some would say you needn't do even that.
If you wanted to mention "This product uses PostgreSQL, which you can
learn more about at http://www.postgresql.org/" then everyone would be
happy. You need not do that, but it'd be a polite thing to do.

Not if you don't want to.

Not required. The strictest reading of the BSD license is that
the notice has to be present somewhere in your distribution.
Putting it on a splash screen is surely more than is needed.
