No; actually the opposite.

If I have a connection, presumably by vpn (this is for postgres), I
want to use it.  If there is no connection to the server, I want to
put things into a local sqlite database, and use that to update the
postgres base later.  I'm looking for a quick way to achieve this,
rather than something with a lengthy timeout
