Support for multi-column aggregate functions

All,

Does the current version of MonetDB support multi-column aggregate functions? I need to create a function which returns the "quantiles" of one column using another column as a weighting. It looks like PostgreSQL supports multi-column aggregates as of 8.2.

I could write an embedded R function to compute this, but want to know if it is even possible to pass in multiple columns.

Thanks,
Dave
