Okay...

Hmm ... this would mean that the implicit parsing of SET TRANSACTION
ISOLATION LEVEL would change (instead of SET / TRANSACTION ISOLATION
LEVEL you'd now tend to read it as SET TRANSACTION / ISOLATION LEVEL)
but I guess that would still not create any parse conflicts. I'm okay
with this as long as we can fix psql's command completion stuff to
handle it intelligently. I hadn't gotten round to looking at that point
yet for the LOCAL case; do you have any thoughts?
