Stefan,
I understand how to create function from sql that receive value as input param(s). But how could i write sql function that receive array of values as input? For example i want to enable stdev function at algebra module, is it possible to do from sql?

You might be interested in these two files it shows how to add a module
to SQL written in the mx language:
http://kinkrsoftware.nl/contrib/monetdb/sphinx.mx
http://kinkrsoftware.nl/contrib/monetdb/sphinx.patch
After that you will still have to 'create function', but that is
relatively simple.
