I don't think -infinity and +infinity are the right terms. For a string or character data type there is no -infinity and +infinity. Similarly for enums. We need to extend UNBOUNDED somehow to indicate the end of a given type in the given direction. I thought about UNBOUNDED LEFT/RIGHT but then whether LEFT indicates -ve side or +side would cause confusion. Also LEFT/RIGHT may work for a single dimensional datatype but not for multi-dimensional spaces. How about MINIMUM/MAXIMUM or UNBOUNDED MIN/MAX to indicate the extremities. -- Best Wishes, Ashutosh Bapat EnterpriseDB Corporation The Postgres Database Company -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
