PostgreSQL flavors

Hello, my first post to the list, thank you for this place to ask questions and get help.

Our management has tasked me with devising a plan to migrate our existing databases from Oracle to PostgreSQL. I'm researching and getting familiar with PostgreSQL before getting a Linux box to start learning and staging. I have a long way to go, but it will be fun.

Out of the gate, I can see different PostgreSQL products - PostgreSQL, PostgreSQLPlus, EnterpriseDB Advanced Server.
For staging I'll likely start with the vanilla version. I've been searching for a comparison of different product sets; I've found some things, but in other places different information. There is a lot to sift through. For example, we are now using non-active Data Guard to a standby for disaster recovery. What is the different on this functionality in the 3 products? Or perhaps there are more products than I've found. Cost will be a factor for us, but I also consider that costs are not only product and maintenance costs, there are DBA and developer migration costs as well.

Any insights or information is appreciated.
