Just so I understand what's going on, I can create a lookup table by pasting this code...
create table taxon (
taxonid serial,
descr text
);
create table gz_life_mammals (
id serial,
taxonid integer, -- use the lookup table
parentid integer -- use the lookup table
);
...into pgAdmin III, right? (I can't use the shell/terminal at the moment, and it will be at least a few weeks before I can get it fixed.) And this script will create TWO tables - gz_life_mammals and a matching "lookup table"?
