I don't know anything about biology so this data might be laughable, but its
based on your original question:

I think I answered my question @
http://www.the-art-of-web.com/sql/lookup-table/
It sounds like the field taxon_id is similar to the field id - it's just
automatically populated by a numerical key. So if I add a new taxon on row
5, then the taxon_id for the following row with change from 5 to 6 -
Sorry, I don't think I specified that at the beginning.
My original/master table has several fields, four of which are relevant to
this hierarchical stuff - id, taxon, parent, parent_id.
The first is a numerical key, from 1 to probably somewhere around 8,000 for
mammals, 1 to 10,000 for birds, et

Yes, I guess it does make sense to keep a copy of your actions.
In the meantime, I now have two new tables with the following schema:
-- Table: public.taxon
-- DROP TABLE public.taxon;
CREATE TABLE public.taxon
(
taxonid integer NOT NULL DEFAULT nextval('taxon_taxonid_seq'::regclass),

David,
Does wrapping the transaction with BEGIN; COMMIT; work as you would expect?
$sql = "BEGIN; with recursive hier(taxon,parent_id) as (
select m.taxon, null::integer

where taxon='Mammalia' --<< substitute me
union all
select m.taxon, m.parent_id

The answer's very thorough, but I don't know how to string two queries and
a function together like that. This doesn't work:
$sql = "select * from gz_life_ma
