How to handle DBConnection.Errror cause by DB?

When the DB closes the connection I have a DBConnection.Error.
I would like in this case to retry the query.
Is it something that could be handle by DBConnection or I have to handle myself?

(My use case is when a DB maintenance is applied by GCP)

There is no retry logic for queries in Ecto/DBConnection as far as I’m aware. The way you retry a query can be pretty implementation-specific so it’s hard to provide a generic interface for that.

Depending on how long the maintenance takes the implementation could be very different. E.g. if the DB was down for half an hour are you sure you still want to run that query? Etc.
