Ah.  I was looking at the mentions of array_prepend() ... but of course
the manual also says that you should use the || operator instead ...
so I guess this mention is sufficient.

The other point about pg_dump failing to correctly restore arrays with
nondefault lower bounds is a good one, though.  We need to think about
how to fix that.
