Add support for postgres databases (#443)
* Refactor : wrap every single SQL query inside an interface * Feat : create every SQL request for postgres * Refactor : rename SQLQueryAbstractFactory to SQLQueryFactory * Feat : add dialect settings to blue map ! * Feat : Create two new storageClass for different storage approche * Feat : add read BYTEA support * Fix : remove unuseful println * Fix : remove edited sql.conf * Refactor / Feat : support for mysql * Lots of tiny tweaks --------- Co-authored-by: Lukas Rieger (Blue) <TBlueF@users.noreply.github.com>
