I did find a few references: https://www.postgresql.org/message-id/1288029716.8645.4.camel%40jdavis-ux.asterdata.local https://www.postgresql.org/message-id/20110111191334.GB11603%40fetter.org https://www.postgresql.org/message-id/1296974485.27157.136.camel@jdavis I'd be interested in ways that we can use a typmod-like concept to improve the type system. Unfortunately, typmod is just not sophisticated enough to do very much because it's lost through function calls. Improving that would be a separate and challenging project. So, I wouldn't spend a lot of time on typmod for multiranges. Regards, Jeff Davis
