Create/Renew Play Data
With a PostgreSQL database you can create a databaseplay database. If it already exists it will be dropped first and recreated. You must be the only connection to the current database. This process is much faster than using the other Create processes on this window.
NOTE: This process creates or renews a duplicate database named the same as your current database plus the 4 letters "play". It can only be run if you have exclusive use of the current database and that there are no connections to the play database. The process also performs the following on the databaseplay database:
