We are still a big Oracle user with maybe 500 Oracle servers. Postgres was an option we selected as another opportunity for deployment because, money-wise, the savings on licensing made it a good choice.

If the application is supported by the database, we can consider using Postgres as a solution. Otherwise, we can't choose it for deployment.
