What Postgres version are you running? We used to have some bugs that
would allow unhelpful error messages like that to emerge in corner
cases. I'm not completely sure that they're all gone. If you're on
7.4.* I'd be interested to see exactly what you did.

If you know what you're doing. The calling query has to specify a
structure for the record.
(Joe, I couldn't find a self-contained example using a function-returning-
record after a bit of searching in the 7.4 docs. Surely there is one?)
