When running sudo openproject configure I am selecting the 'reuse' database option.  I get the following error...

[openproject] ./bin/postinstall
W, [2019-12-27T16:23:57.747864 #3237]  WARN -- : hook registered
/opt/openproject/lib/tasks/database.rake:49:in `rescue in block (3 levels) in <top (required)>': ---------------------------------------------------
DATABASE UNSUPPORTED ERROR

Database server is not PostgreSql. As OpenProject uses non standard ANSI-SQL for performance optimizations, using a different DBMS will break and is thus prevented.

For more information, see the system requirements.

 (StructuredWarnings::StandardWarning)

The external DB server is a fresh install of PostgreSql 10.11.  I have created a blank openproject DB.  I have confirmed DATABASE_URL looks to be getting set properly with the information provided during the configuration wizard.

postgres=# \l
                                    List of databases

-------------+-------------+----------+-------------+-------------+-----------------------
 openproject | openproject | UTF8     | en_US.UTF-8 | en_US.UTF-8 |

Am i missing something on the database setup?  Any help would be greatly appreciated.
