DROP TABLE wildcard - Mailing list pgsql-general

Is it possible to drop multiple tables with SQL on the system tables:

I tried this:

DROP TABLE from pg_tables where tablename LIKE 'table_num_%';

Which for whatever reason would delete 0 items despite it should have
matched on several.

Of course I'm not even sure pg_tables would be the smart place to make the
delete from?

Thanks.
