Hi John,

Between RC2 and RC4 there is one new table and one new column on an
existing table.  Just apply the following SQL at a psql prompt and
then upgrade the Evergreen software pieces.  (Copied to -dev, as
that's where this should really go.)

--------------------- start of update --------------------

BEGIN;

CREATE TABLE actor.usr_org_unit_opt_in (
       id              SERIAL                          PRIMARY KEY,
       org_unit        INT                             NOT NULL
REFERENCES actor.org_unit (id),
       usr             INT                             NOT NULL
REFERENCES actor.usr (id),
       staff           INT                             NOT NULL
REFERENCES actor.usr (id),
       opt_in_ts       TIMESTAMP WITH TIME ZONE        NOT NULL DEFAULT NOW(),
       opt_in_ws       INT                             NOT NULL
REFERENCES actor.workstation (id),
       CONSTRAINT usr_opt_in_once_per_org_unit UNIQUE (usr,org_unit)
);

ALTER TABLE action.hold_request ADD COLUMN thaw_date TIMESTAMP WITH TIME ZONE;

COMMIT;

--------------------- end of update --------------------
