We've had this discussion before and I'm still unpersuaded by your
position.  I *never* write "IF FOUND THEN" except immediately after
the statement where I expect that variable to be set, and I submit
that anyone who who does write code that relies on certain statements
not setting FOUND is, IMO, depending on a bug.  We don't and shouldn't
have a policy of making future PostgreSQL releases bug-compatible with
previous releases.
