Thank you Jon -- thats the exact sort of trick I was hoping for.
Cheers!

Does anyone have a trick to list all columns in a db ?
No trickery, just exploit the availability of the SQL standard
information_schema views:
select table_schema, table_name, column_name
from information_schema.columns
where table_schema not in ('pg_catalog','information_schema')
order by 1,2,3
If you want an equivalent that uses pg_catalog (non-portable
outside of PostgreSQL) you could instead do:
select n.nspname as table_schema, c.relname as table_name,
a.attname as column_name
from pg_catalog.pg_attribute a
join pg_catalog.pg_class c on (a.attrelid = c.oid)
join pg_catalog.pg_namespace n on (c.relnamespace = n.oid)
where c.relkind in ('r','v') and a.attnum > 0
and n.nspname not in ('pg_catalog','information_schema')
order by 1,2,3
