I understand the "merovingian" is the new and updated program to handle instance administration issues.

Can you please provide more information on how I can use "merovingian" to START/STOP MonetDB instances?

merovingian has a manpage, and you want to look at the monetdb manpage too. You may find a presentation I recently gave somewhat interesting: http://homepages.cwi.nl/~fabian/Publications/Merovingian%20MADAM.pdf I think merovingian cannot do exactly what you do right now, as it only manages one dbfarm, but it does not know a "default" database as well. If you have more specific questions, I'm happy to answer them.
