Thanks. I've just pushed something.
I ended up deciding that we owe the user a bit more of an explanation
of how they might work around the problem. Of course, a partitioned
table index build is likely to take much longer than an index build on
a normal table, since most likely a partitioned table is larger. So I
went on to explain how they might minimise the time where writers will
be blocked by creating indexes concurrently on each partition first.
