Delphix virtualizes Postgres as well as Oracle and SQL Server. Delphix is software that runs as a VM. Delphix connects to a source database, collects what is called a "timeflow." A timeflow is is collection of data from the source database allowing Delphix to spin up clones on a target machine anywhere with in a time window covered by timeflow. Timeflow is by default two weeks. Data older than the two weeks that is not being used is purged. Delphix looks like a NAS to the target databases, the clones. New clones just point to existing datablocks on Delphix so new clones take up no new space and can be created in minutes. The clones can be refreshed from the source in minutes, branch to create data control which is to data what source control is to code, and can be rolled back to allow rerunning destructive QA tests over and over.
