Hmm, how about:

Allow Unicode escapes, e.g., E'\u####' or U&'\####', to represent
any character available in the database encoding, even when that
encoding is not UTF-8.

which I suggest as I recall more clearly that the former condition
was not that such escapes were always rejected in other encodings; it was
that they were rejected if they represented characters outside of ASCII.
(Yossarian let out a respectful whistle.)

My inclination is to give at least one example each of the E and U&
form, if only so the casual reader of the notes may think "say! I hadn't
heard of that other form!" and be inspired to find out about it. But
perhaps it seems too much.
