Alfresco installation procedure is rather confusing. Either I need some things or I don't I can never tell so I need some help. For one, do I install postgresql myself (wiki.alfresco states I need at least postgresql 9.2 but on doc.alfresco it says I need postgresql jdbc connector 9.3 so I guess I really need postgresql 9.3) or use the postgresql that is supplied with the installer? If I use the one supplied with the installer do I still need the jdbc connector and how would I make a database and user for postgresql or is none of that required?
