Two ways to build a range:

select '[2024-02-18, 2024-02-20)'::tstzrange;
tstzrange
-----------------------------------------------------
["2024-02-18 00:00:00-08","2024-02-20 00:00:00-08")

or

select tstzrange('2024-02-18', '2024-02-20', '[)');
tstzrange
-----------------------------------------------------
["2024-02-18 00:00:00-08","2024-02-20 00:00:00-08")
