Take a look of Globular, I think it is exactly what you looking for. https://github.com/davecourtois/Globular
Binaries for windows and linux are available, all you have to do it’s to unzip it start the server. Micro Service link SQL (mySql, odbc), LDAP, SMTP, persistence (MongoDB), storage(LevelDB, Big Cache) are already creates. I can append Postgresql as you need in the list of driver whiout to much problem.
