For every one person who reads the mailinglist archives, I bet there are dozens who merely read the product documentation and never find the workaround/solution. Perhaps a note below the table here: http://www.postgresql.org/docs/8.0/interactive/functions-aggregate.html#FUNCTIONS-AGGREGATE-TABLE would be a good place. If it is already somewhere in the docs; perhaps the page I linked should refer to the other page as well.
