wait, what is a tsrange? the standard textsearch data types in postgres are tsvector and tsquery,

never mind,  I should have known, its a timestamp range.   ...


when you do updates, are you changing any of the indexed fields, or just "value" ?
Yeah, it's a temporal table, so "updates" involve modifying the period column for a row to set its end ts, and then inserting a new row with a start ts running on from that.

Of course, the adds are just inserting new rows.
