Re: How to delete all operators

You can make a function to do this.

CREATE FUNCTION drop_operators(text) RETURNS BOOL AS
$$
DECLARE
op record;
BEGIN
FOR op IN SELECT opname
FROM pg_operator as o left join pg_namespace as n on (
o.oprnamespace = n.oid)
WHERE nspname = $1
LOOP
EXECUTE 'DROP OPERATOR '||quote_literal(op.opname)||';';
END LOOP;
RETURN TRUE;
END;
$$ LANGUAGE 'plpgsql' IMMUTABLE;

And so: SELECT drop_operators('public');
