Removes empty filegroups from SQL Server databases.
Removes one or more filegroups from SQL Server databases after validating they contain no data files. This command is useful for cleaning up unused filegroups after moving data to different filegroups or during database reorganization projects. The function performs safety checks to ensure filegroups are empty before removal and provides detailed error messages if removal fails due to dependencies or constraints.

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
