You could do:


if you have permissions for that.  (It would delete functions and so on
as well, not just tables.)

Or you could do it in shell script:

psql -t -d my_dbname -c "SELECT 'DROP TABLE ' || n.nspname || '.' ||
c.relname || ' CASCADE;' FROM pg_catalog.pg_class AS c LEFT JOIN
pg_catalog.pg_namespace AS n ON n.oid = c.relnamespace WHERE relkind =
'r' AND n.nspname NOT IN ('pg_catalog', 'pg_toast') AND
pg_catalog.pg_table_is_visible(c.oid)" >/tmp/droptables

psql -d my_dbname -f /tmp/droptables

      Son of man came with the clouds of heaven, and came to
      the Ancient of days, and they brought him near before 
      him. And there was given him dominion, and glory, and 
      a kingdom, that all people, nations, and languages, 
      should serve him; his dominion is an everlasting 
      dominion, which shall not pass away, and his kingdom 
      that which shall not be destroyed."
