How to create an index on timestemp in jsonb?

Question

PostgreSQL

Is it possible in postgresql to add an index to one of its timestamp keys on a jsonb field containing a large json? Or the index in any case, how not to be perverted, will be textual and will not do the weather?

Answer 1

Technically, this will be a functional index, but easily
In order for it to be used, you will need to cast to the timestamp in the request as well.
