Last night I was reviewing my proposed patch from this thread, to try
to address other expressed concerns, and noticed that I had used this
language from the SQL spec in the patch.  I see your point now. 
Without the same context as the spec, and when intended for a
different audience, this language probably isn't the best.  It now
also occurs to me that the spec is a copyrighted work, and it probably
isn't appropriate to copy a chunk that big into PostgreSQL docs.
I'll write something in my own words to replace this.
Thanks for the input, and sorry for misunderstanding.
