Congratulations on the decision and welcome. As an overview, there is the PostgreSQL *project* which is run by the PostgreSQL Global Development Group (PgDG) with contributors around the world most of whom work for a variety of companies that either use or support PostgreSQL. PostgreSQL is BSD-licensed open-source software. PgDG operates these mailing lists.
Within the PostgreSQL ecosystem you will find numerous commercial and non-commercial entities that provide: -Custom/commercial/extended products based on PostgreSQL (i.e. EnterpriseDB and others) - some of which are designed to provide a level of Oracle compatibility -Commercial and open-source tools that extend, support or work with PostgreSQL (you may want to look at Ora2Pg - a tool to migrate Oracle to PostgreSQL) -Development services -Training -DBA and support services (i.e. PGExperts) -User-groups (very helpful but I don't see one in Florida: http://www.postgresql.org/community/user-groups/) -Conferences (http://www.postgresql.org/about/events/) -Books and magazines I'd agree with your plan to start with the core open-source PostgreSQL software to learn then progress to other products/projects as needs dictate.
