Re: Checkpoint_segments optimal value

SELECT account.id, account.organization_id, run.application_id, work_unit.script, work_unit.id, work_unit.start_time, run.id, work_unit.priority  FROM work_unit, run, account  WHERE  work_unit.status = 3 AND work_unit.run_id = run.id AND work_unit.type != 1 AND run.status = 1 AND run.account_id = account.id

that query is an implied 3-way join.  it would be clearer to write it like...

SELECT account.id, account.organization_id, run.application_id, work_unit.script, work_unit.id, work_unit.start_time, run.id, work_unit.priority 
    FROM work_unit
        JOIN run ON work_unit.run_id = run.id
        JOIN account  ON run.account_id = account.id
    WHERE work_unit.status = 3 AND work_unit.type != 1 AND run.status = 1;

postgres would (or at least should) treat this exactly the same, but its clearer what the query is doing when its written this way.
