I'm looking at modifications to dblink to allow it to make use of table 
functions. One item which is very much needed is the ability to define 
dblink as returning setof record, so that it can return a tuple as 
described at runtime in the query string.

I'm trying to come up with the best method to pass the query string 
columndef, or better yet the tuple description, to the function. Any 
suggestions on an approach?

Thanks,

Joe
