Its through perl-dbi using ->prepare, ->execute.. is that what you
mean? Also this is with mod_perl and Apache::DBI.
So a typical transacion looks like
connect to postgres;
begin;
do stuff here;
commit or rollback;
(next page load)
begin;
....
so potentially a database connection/session is reused on the next
page load if that makes a difference.
