Losing samples on browser refresh

Hi Ines,

I tried to look more into the issue with setting force_stream_order to True. I thought the error was coming from the way I was loading the data but then I tried with a local file and I still get the following error "AssertionError: RepeatingFeed requires a database connection".
I am using a PostgresqlExtDatabase, could that be the cause of the problem?

Thanks for your help
