Hi Jar,
Knowage CE installer requires MySQL. You can finalize an installation on MySQL, then switch to PostgreSQL this way:
- migrate the whole 2 schemas (structure + data) to PostgreSQL;
- fix resources in Knowage-Server-CE\conf\server.xml;
- fix SQL dialect in Knowage-Server-CE\webapps\knowage*\WEB-INF\classes\hibernate.cfg.xml;
- fix SQL dialect in Knowage-Server-CE\webapps\knowage\WEB-INF\classes\quartz.properties.
In the end please check logs after starting Knowage CE in order to debug any issue.
Best regards,
Francesco
