I know that sys.modules[__name__] gives the module object for the current 
module.  You could do:

m = sys.modules[__name__]  # M now current module object
func = m.__dict__ [fs]     # func has function named by string fs
func()

If func isn't in the current module, replace __name__ with 'Foo'.  Add 
try/catch as appropriate in case fs doesn't exist in module M.

If your database stores the function arguments in the same string as the 
function name, you'll have to parse them out separately.

I make no claims to this solution being optimal, as it pretty much 
stretches my knowledge of Python modules and reflection.
