I should have provided details of this in the email. SQL99 details the
baviour as follows:

If TEMPORARY is specified and ON COMMIT is omitted, then ON COMMIT
DELETE ROWS is implicit

This might give users a bit of a surprise so the effective behaviour is ON
COMMIT PRESERVE ROWS.

As for your question (and, perhaps, SQL99) I don't seen how it makes any
sense to specify ON COMMIT outside of a transaction block.
