Вопрос
I have a spatio-temporal database in Postgresql that is continuously updates. I was wondering if there is a technique for continuous query in this database? for example I have temperature data that updates every minute in the database for specific area. I want to perform aggregate queries to show me the temperature every hour (aggregated value).
Решение
No, you can't continuously update query, but you can receive notification on events of importance and reissue your query.
