Yeah, that's one way.  It also strikes me that hstore itself provides a
usable solution to this problem, though only for simple-string values.
That is, you could do something like
create function myfunc(hstore) returns ...
select myfunc('tag1' => '42' || 'tag2' => 'foobar' || ...);

Or, with the new variadic function support,
create function myfunc(variadic hstore[]) returns ...
select myfunc('tag1' => '42', 'tag2' => 'foobar', ...);

which is just a couple of quote marks away from the syntax Pavel
wants.
