We do not support Azure Database for PostgreSQL – we support Azure MS SQL. We do not support Amazon RDS for either Oracle or MS SQL – we support Amazon RDS for PostgreSQL.
For each database, we try to test the type that will scale the best and provide the best experience for our clients. If we have not tested a product (the ones listed above), we cannot guarantee how well it scales. So the databases listed in the Platform Support Guide are the ones we have tested and approved.
