PostgreSQLconstructs that, and then attempts to apply the cast.  There's no conversion path from that to TSTZRANGE, so
thesystem complains.  It's imaginable, I guess, that such a path could be added, but the right way to do it is what you
dohere:

Or do something like:

  select '[2023-10-25 14:33:00, 2023-10-25 15:56:00)'::TSTZRANGE;
                        tstzrange
