I checked a code from datetime parser, and there we are not consistent
postgres=# select '1973-07-15 08:15:55.33+02'::timestamptz;
postgres=# select '1973-07-15 08:15:55.33+02.2'::timestamptz;
ERROR: invalid input syntax for type timestamp with time zone: "1973-07-15
LINE 1: select '1973-07-15 08:15:55.33+02.2'::timestamptz;
It allows only integer
but AT TIME ZONE allows double (but decimal parts is ignored quietly)
postgres=# select make_time(10,20,30) at time zone '+10.2';
so I propose (and I implemented) a variant with int as time zone
and we can (if we would) implement next one with text as time zone
