Ok, I did see the autocommit flag setting in DBD:Pg when I starting reading up
on the DBI/DBD interfacing methods so I guess I could recode for that. However,
how do you "maintain" the current transaction open if your script is writing
pages to the web. Even in mod_perl I think that there is a commit after the
script ends, no?
