This is a Postgres extension that provides a range_agg aggregate function. It takes any [Postgres range type] and combines them, sort of like [string_agg, array_agg, json_agg, etc] There are three forms, depending on whether or not you want to permit gaps & overlaps. If you call range_agg(anyrange) (with just a single range parameter), then it will raise an error if a gap or overlap is detected, and on success it will return a single range.
