Download Database as TSV file

The short answer is that I don’t believe that you can because I don’t believe that it is available in that format. It is far too large and complex, as shown in the schema pointed to by @InvisibleMan78 in Mbdump.tar.bz2 Artist List. If you want to extract a portion of the database into a TSV file, then I suggest that you consider setting up a copy (or mirror) of the database locally, and then extract the information as required.
