    Ok, I have a trigger set up on the following (stripped down) table:

    CREATE TABLE members (
    member_id   bigint,
    member_status_id   smallint,
    member_is_deleted    boolean
    );

    Here's a shortened version of the trigger function:

    CREATE OR REPLACE FUNCTION update_member() RETURNS TRIGGER AS $um$
    DECLARE
        status_deltas integer[];
    BEGIN
        IF(NEW.member_status_id != OLD.member_status_id AND
    NEW.member_is_deleted IS NOT TRUE) THEN
           status_deltas[NEW.member_status_id] := 1;
           status_deltas[OLD.member_status_id] := -1;
        END IF;
        /*and after a couple more such conditional assignments I use the
    values in status_deltas to update another table holding status
    totals here*/
    END;
    $um$ LANGUAGE plpgsql;

    on the two lines that access set array values I'm getting the
    following
    error:

    ERROR:  invalid array subscripts

    What gives?

What values are being used for member_status_id?

1,  2, and 3
