Hi, I'm having trouble loading these files. After some failed attempts, I've managed to go to the PostgreSQL shell on pgAdmin and run

\i <PATH TO DOWNLOADED precints20.sql

as suggested in https://stackoverflow.com/a/75131834.

This attempts a reload but in I error out with

psql:<PATH>/precincts20.sql:9910036: ERROR:  role "sbaltz" does not exist
psql:<PATH>/precincts20.sql:9910037: ERROR:  role "reader" does not exist

(where I've hidden my own paths with PATH).

This seems to be due to the last few lines in the postgresql dump:

GRANT SELECT ON TABLE public.precincts20 TO sbaltz;
GRANT SELECT ON TABLE public.precincts20 TO reader;
