Note, this only runs if you explicitly call L</disconnect> on the
storage object.
+=item on_connect_call
+
+A more generalized form of L</on_connect_do> that calls the specified
+C<connect_call_METHOD> methods in your storage driver.
+
+ on_connect_do => 'select 1'
+
+is equivalent to:
+
+ on_connect_call => [ [ do_sql => 'select 1' ] ]
+
+Its values may contain:
+
+=over
+
+=item a scalar
+
+Will call the C<connect_call_METHOD> method.
+
+=item a code reference
+
+Will execute C<< $code->($storage) >>
+
+=item an array reference
+
+Each value can be a method name or code reference.
+
+=item an array of arrays
+
+For each array, the first item is taken to be the C<connect_call_> method name
+or code reference, and the rest are parameters to it.
+
+=back
+
+Some predefined storage methods you may use:
+
+=over
+
+=item do_sql
+
+Executes a SQL string or a code reference that returns a SQL string. This is
+what L</on_connect_do> and L</on_disconnect_do> use.
+
+It can take:
+
+=over
+
+=item a scalar
+
+Will execute the scalar as SQL.
+
+=item an arrayref
+
+Taken to be arguments to L<DBI/do>, the SQL string optionally followed by the
+attributes hashref and bind values.
+
+=item a code reference
+
+Will execute C<< $code->($storage) >> and execute the return array refs as
+above.
+
+=back
+
+=item datetime_setup
+
+Execute any statements necessary to initialize the database session to return
+and accept datetime/timestamp values used with
+L<DBIx::Class::InflateColumn::DateTime>.
+
+Only necessary for some databases, see your specific storage driver for
+implementation details.
+
+=back
+
+=item on_disconnect_call
+
+Takes arguments in the same form as L</on_connect_call> and executes them
+immediately before disconnecting from the database.
+
+Calls the C<disconnect_call_METHOD> methods as opposed to the
+C<connect_call_METHOD> methods called by L</on_connect_call>.
+
+Note, this only runs if you explicitly call L</disconnect> on the
+storage object.
