I have tried this but no go:
network=# create temp table chl() inherits (configurations.tp_transactions);
ERROR:  inherited relation "tp_transactions" is not a table

This does not work either:
network=> CREATE TEMP TABLE myt OF configurations.tp_transactions;
CREATE TABLE
network=> \d myt
               Table "pg_temp_11.myt"
     Column     |         Type         | Modifiers
---------------+----------------------+-----------
  id            | integer              |
<snip>
  amount        | numeric              |
  pp_value      | numeric              |
Typed table of type: configurations.tp_transactions

network=> insert into myt select * from configurations.tp_transactions where trans_id=920787;
INSERT 0 1

network=> select configurations.myself(myt.*) from myt;
ERROR:  function configurations.myself(myt) does not exist
