I just don't understand why you think there should be multiple
spellings of the same bound. Generally, canonicalization is good.
One of my fears here is that at least some people will get confused
and think a bound from (minvalue, 0) to (maxvalue, 10) allows any
value for the first column and a 0-9 value for the second column which
My other fear is that, since you've not only allowed this into the
syntax but into the catalog, this will become a source of bugs for
years to come. Every future patch that deals with partition bounds
will now have to worry about testing
unbounded-followed-by-non-unbounded. If we're not going to put back
those error checks completely - and I think we should - we should at
least canonicalize what actually gets stored.
