FreeRADIUS / PostgreSQL?

Hello Users -- I'm writing again to verify whether or not my initial question submitted to the list was seen. Is there anyone on-list who is able and willing to assist in troubleshooting a PostgreSQL integration with FreeRADIUS? If the initial message was not received for whatever reason, I'll be happy to provide the details again. If not PostgreSQL, does anyone have expertise in working with MariaDB/MySQL integration as a user / accounting store for FreeRADIUS? Thanks in advance for your patience and assistance. MD
