Yep, that's just what I needed, thanks. I think I'll send a patch for the "Cursors" section of the PL/pgSQL documentation that mentions this. Would have saved me a bunch of hassle.
So would have reading two more sentences of the docs, which state, to my surprise (that I missed it!), “As with `SELECT INTO`, the special variable <code>FOUND</code> can be checked to see whether a row was obtained or not.” D’oh!
So now I've got things working the way I need, and I've blogged about these SQL pathologies so that I don't forget.
