Quite often errors like these comes from the underlying data connection drivers and they don't provide us more details.

Thanks for the response.

Is there a way to see the query that's generated so I could investigate the data that's being pulled?

Given I'm using postgres I'm assuming you're referring to npgsql as the underlying data drivers?
If so, would i be able to debug that library with the same query generated by Sqlprovider?

Usually this FSharp.Data.Sql.Common.QueryEvents.SqlQueryEvent |> Event.add (printfn "Executing SQL: %s") but I suppose your error is before that, already when connecting to the server?

We are trying to pass these underlying errors without touching them. Because this is probably not SQLProvider error, I would try to google "Exception while reading from stream npgsql"
