Moving a database between servers

I am trying to move a postgresql database from one
server to another.  The original server is 7.1.3, and
the new one is 7.3.4.

I went on the old and used the command:
pg_dumpall > dump

On the new:
psql -e < dump

I get this for multiple functions. (Error follows
surrounded by *****'s)

CREATE FUNCTION "transaction_visit" (integer) RETURNS
integer AS '
    select visit_id
      from (
             select *
               from visit_history as vh
              where sequence = (
                      select max(sequence)
                        from visit_history
                       where vh.firm_id = firm_id
                         and vh.patient_id =
patient_id
                         and vh.visit_id = visit_id
                    )
           ) as v
     where v.firm_id = (select firm_id from
current_transaction)
       and v.patient_id = $1
       and v.person_id = (select person_id from
current_transaction)
       and v.inked is null
' LANGUAGE 'sql';

****ERROR:  Relation "current_transaction" does not
exist****


The current_transaction is a TEMPORARY table created
like this:
CREATE FUNCTION "open_session" (integer,integer)
RETURNS integer AS '
    create temporary table current_transaction as
    select $1 as firm_id,
           $2 as person_id,
           timeofday()::timestamp as
transaction_timestamp,
           timeofday()::timestamp as
history_timestamp;
    select 1;
' LANGUAGE 'sql';





How do I get these functions to import correctly if it
fails due to this "current_transaction" table not
being found? (only due to it being a temporarily table
created by a different command)
