Re: DBI connect returning an empty hash

Nevermind; sorry to have bothered this list about this.  It turns out
that when DBI/DBD::Pg is working correctly, the database handle does
look like a blessed empty hash, so that is not my problem.  There must
be something wrong with the way I am trying to cache the handle in my
module.

Thanks anyway,
Scott
