Is this a good idea: I can probably find this answer by looking at whatever uses getIdField, but it's just as well to presume the answer is "No" for now, and leave the code as-is.

Should this be set to false? Do we even need these sequences? (If not, then eliminate all references to archive_ar_id_seq and externallinks_el_id_seq.) My guess is that I don't need it, since there's no page_page_id_seq sequence.
