You could do something like:
postgres=# select (information_schema._pg_expandarray('{1,5,3}'::int[])).x order by x;x
---135
(3 rows)
That would be a whole lot less unappetising if the function wasn't an internal
function that someone might want to change without breaking random regression
tests. It seems likely the day that happens will be the day that we provide an
SQL standard UNNEST anyways though.
