Where session = connection (whether from psql, DBI, etc), yes?

To be honest, I'm not 100% sure I was reconnecting. I think I had it in
my head that the perl instance would be related to role or database, so
was creating new databases with new roles and testing code straight away.

I thought I tried reconnecting, since that's obvious too, and in my
limited local testing that seems to work; in staging/production environs
its trickier to bounce the apps, so maybe I haven't been restarting them
when I thought I was.

Thanks for the advice; it sounds like I have been missing the obvious
here, so will head off and do some more checking.

Thanks for the quick response!
