If I'm following correctly, Peter's specifically talking about:
[ USING ( <replaceable class="parameter">expression</replaceable> ) ]
[ WITH CHECK ( <replaceable
class="parameter">check_expression</replaceable> ) ]
Where the USING parameter is 'expression' but the WITH CHECK parameter
is 'check_expression'. He makes a good point, I believe, as
"expression" is overly generic. I don't like the idea of using
"barrier_expression" though as that ends up introducing a new term- how
about "using_expression"?
This would need to be reflected below in the documentation which talks
about "expression" as the parameter to "USING", but I can certainly
handle cleaning that up.
Thanks!
