Mismatched parentheses when creating a rule with multiple action queries

PostgreSQL 7.3.2.
The parser does not seem to like semicolon between action queries:
(Mismatched parentheses)

So, it makes impossible to create a rule with more than one action
query.
Or am I missing something?

CREATE RULE my_insert_rule AS ON INSERT
TO my_view
DO INSTEAD
(
INSERT INTO my_table1... ;
INSERT INTO my_table2...
);

The rule with just one action works fine:
DO INSTEAD
(
INSERT INTO my_table1...
);
