=head1 NAME
DBD::Gofer::Policy::rush - The 'rush' policy for DBD::Gofer
=head1 SYNOPSIS
$dbh = DBI->connect("dbi:Gofer:transport=...;policy=rush", ...)
=head1 DESCRIPTION
The C<rush> policy tries to make as few round-trips as possible.
It's the opposite end of the policy spectrum to the C<pedantic> policy.
Temporary docs: See the source code for list of policies and their defaults.
In a future version the policies and their defaults will be defined in the pod and parsed out at load-time.
