On the bottom of this page (http://www.postgresql.org/download/), there is a list of other ways to get Postgres. Mammoth is included among others. Can we get EnterpriseDB Postgres listed there?
It should say:
EnterpriseDB Postgres (link to http://postgres.enterprisedb.com) - includes consistent cross-platform GUI installers that deliver the most commonly needed PostgreSQL components and add-ons.
