Don't include the timestamp. Wildcards are permitted. *Be careful with this syntax!* If the named migration(s) depend on other migrations that haven't been run, the migration will fail. .EXAMPLE rivet.ps1 -Pop Reverts the last migration script. .EXAMPLE rivet.ps1 -Pop 5 Demonstrates how to revert multiple migrations. The last `-Count` migrations will be popped. .EXAMPLE rivet.ps1 -Pop 'AddTable' Demonstrates how to pop a specific migration. Wildcards supported. Will match either the migration's name or ID. .EXAMPLE rivet.ps1 -Redo Reverts the last migration script, then reapplies its. Equivalent to rivet.ps1 -Pop rivet.ps1 -Push .EXAMPLE rivet.ps1 -Push -Environment Production Demonstrates how to migrate databases in a different environment. The `Production` environment should be specified in the `rivet.json` configuration file. .EXAMPLE rivet.ps1 -DropDatabase Demonstrates how to drop the database(s) for the current environment.
