The following should recreate the public schema:
CREATE SCHEMA public;
GRANT ALL ON SCHEMA public TO public;
COMMENT ON SCHEMA public IS 'Standard public schema';
You could practice by creating a test database from template0, then
use pg_dump to get a "before" dump of the test database, drop and
recreate the public schema, use pg_dump to get an "after" dump,
then compare the dumps with a command like "diff". The before and
after dumps should be identical.
When you're done messing with template1, you could dump it and
compare that dump to a dump of a database created from template0.
The comparison should show if you missed anything.
