Answer 1

If you have object in updates column for eg:
{
"time": {
"__type": "Date",
"iso": "2021-10-12T12:10:54.224Z"
},
"userId": "Hd37AyKJsN",
"to": "opened",
"role": "admin",
"from": "closed"
}
Then query would look something like:
select * from orders where (updates #>> 'time,iso')::timestamp Between NOW() - INTERVAL '5 day' AND NOW();
If you have array in updates column for eg:
[{
"time": {
"__type": "Date",
"iso": "2021-10-12T12:10:54.224Z"
},
"userId": "Hd37AyKJsN",
"to": "opened",
"role": "admin",
"from": "closed"
}]
Then query would look something like:
select * from orders where (updates #>> '0,time,iso')::timestamp Between NOW() - INTERVAL '5 day' AND NOW();
