The one-click installer is the pure open source installer that we
build for the community.

There are two versions of Postgres Plus:

- Standard Server (or just Postgres Plus) is also pure Open Source,
but comes bundled with additional software that is not in the
PostgreSQL installer - for example, ODBC/JDBC drivers, Slony and
PostGIS.

- Advanced Server is not Open Source, and includes our Oracle
compatibility, replication/migration tools, GridSQL, DBA Management
Server and other tools.

(note that features vary slightly by platform).

See the 'What version is right for you' section of

Yeah, that is a little confusing. I think what it's trying to tell you
is what amount of support you get for the subscription level you buy
*should you choose to buy support from us*. Obviously you do not have
to buy anything from us to use the PostgreSQL or Postgres Plus
Standard Server packages for development or production.

I'll ask the marketing folks to look at improving that.
