I can make them handy, but when you say they don't work do you mean  
it crashes, or what exactly. I ask only because the DBMS seems to  
have varying support for the method overall. below 7.3 not being able  
to support the call at all, below 8.0 not supporting argument names  
and below 8.1 not supporting argument modes. when I say not  
supporting, I mean there is not column for the data in 'pg_proc'. I  
didn't actually try this against those over servers, but looked it up  
in the respective documentation of each server version. I suppose  
that information might reside in another table, I will have to  
install the other versions and find out.

good to know, would you like me to resend them?

My bad... I had made a number of changes in that file originally,  
then after some discussion, changed direction. I must have missed the

Also good to know, changed and the patch is attached.
