Hm, yeah. Anyone have ideas for better wording for the original error message, or a DETAIL or HINT addition? The key point here is that the number of _hypothetical_ arguments and the number of ordered columns must match, but we don't currently exclude the possibility that a user-defined hypothetical set function might have additional non-hypothetical args. The first alternative that springs to mind is: ERROR: Incorrect number of arguments for hypothetical set function DETAIL: Number of hypothetical arguments (3) must equal number of ordered columns (2) -- Andrew (irc:RhodiumToad) -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
