I've found it useful to explore the information_schema schema by doing:

set search_path=information_schema; -- Lets just look at the system tables.
\d -- Show me all the tables.
...
(40 rows)

then
select * from some-likely-looking-table limit 20;

In this case, I quickly found a table called "columns", so you can do:
select table_name from information_schema.columns where
column_name='last_modified';

Of course you could be a wuss and actually read the documentation ;-)
