As far as I remember if you send NULL, you are saying that
the string that PgDatabase uses is empty rather than being say
"dbname=test", and that it should try to connect ?using defaults?,
whereas if you just db(), you are saying, this instance isn't
initialised, create it, but don't connect. I'm afraid I can't
UTSL at the moment...
