Yes, it looks pretty standard.  But you need to think harder about
exactly what you intend to do when two people try to edit the same
record concurrently.  ("Use a cursor" does not answer that question
at all.)  That's a bit off-topic for pgsql-interfaces though; I'd
recommend discussing it in pgsql-sql.

Not really.  I'd not bother with binary cursors at all.  You're just
opening yourself up to portability problems, and you're not saving
anything meaningful when you're fetching just one row.
