Hmm. Yes, it looks like this is probably the same or a related issue.

In contrib/dblink, see dblink.c for a couple of examples (dblink(),
dblink_get_pkey()), or look at pg_stat_get_backend_idset() in the
backend code. I haven't written a C-function returning a setof composite
type yet, but probably will soon, because I'll need it for testing (and
ultimately for the regression test script).
Thanks for the help!
