plpgsql default arguments

[Greg Lindstrom <greg.lindstrom@xxxxxxxxxxxxxxxxx>]

Hello-

I am running postgres on a Linux system and have been using plpgsql to 
write functions.  Is there a way to specify default arguments?  For 
example, I would like to offer the user to specify a date to use in my 
function but if no date is specified I would like to use the current 
date.  Easy to do in C, C++, Perl, and Python (and, I assume Java), but 
I can't find anything in the documentation or on Google.  Is it possible 
in plpgsql?

Thanks,
--greg
