Close DAZ Studio
Open Install Manager
Download and install the version of PostGreSQL appropriate for your OS
Download and install the Conversion product "PostgreSQL CMS From Valentina CMS Conversion". (If it takes less than a couple of seconds it didn't work, likely due to a corrupt Valentina Database.)
