That is a very good point. Canonicalizing to an unbounded range doesn't work, because, as it stands, the ranges '[1, INT_MAX]' and '[1,)' are *not* equal. So the only remaining option is to canonicalize to the closed form always. I still think we should strive for consistency here, so let's also make '[]' the default flags for the range constructors. best regards, Florian Pflug -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
