This usually does it for me:-
select
*from
-- information_schema.tables
pg_catalog
.pg_tables--WHERE
-- table_schema = 'public'
--ORDER BY
-- table_name

Sorry, I meant to send this to the list:
We have a handful of tables that are quite large and take several hours to

accounts for system load. I want to pull the list of all tables and exclude
these large tables from the list, then run the vacuum on the remaining tables
once a week to avoid transaction ID wraparound failures.
