NAME
       DBD::Gofer::Policy::Base - Base class for DBD::Gofer policies
SYNOPSIS
         $dbh = DBI->connect("dbi:Gofer:transport=...;policy=...", ...)
DESCRIPTION
       DBD::Gofer can be configured via a 'policy' mechanism that allows you
       to fine-tune the number of round-trips to the Gofer server.  The
       policies are grouped into classes (which may be subclassed) and
       referenced by the name of the class.
       The DBD::Gofer::Policy::Base class is the base class for all the policy
       classes and describes all the individual policy items.
       The Base policy is not used directly. You should use a policy class
       derived from it.
POLICY CLASSES
       Three policy classes are supplied with DBD::Gofer:
       DBD::Gofer::Policy::pedantic is most 'transparent' but slowest because
       it makes more  round-trips to the Gofer server.
       DBD::Gofer::Policy::classic is a reasonable compromise - it's the
       default policy.
       DBD::Gofer::Policy::rush is fastest, but may require code changes in
       your applications.
       Generally the default "classic" policy is fine. When first testing an
       existing application with Gofer it is a good idea to start with the
       "pedantic" policy first and then switch to "classic" or a custom
       policy, for final testing.
POLICY ITEMS
       These are 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.
       See the source code to this module for more details.
POLICY CUSTOMIZATION
       XXX This area of DBD::Gofer is subject to change.
       There are three ways to customize policies:
       Policy classes are designed to influence the overall behaviour of
       DBD::Gofer with existing, unaltered programs, so they work in a
       reasonably optimal way without requiring code changes. You can
       implement new policy classes as subclasses of existing policies.
       In many cases individual policy items can be overridden on a case-by-
       case basis within your application code. You do this by passing a
       corresponding "<go_<policy_name">> attribute into DBI methods by your
       application code.  This let's you fine-tune the behaviour for special
       cases.
       The policy items are implemented as methods. In many cases the methods
       are passed parameters relating to the DBD::Gofer code being executed.
       This means the policy can implement dynamic behaviour that varies
       depending on the particular circumstances, such as the particular
       statement being executed.
