One way to achieve this using the proposed SQL function is to create a
C function in a module like injection_points, which combines injection_notice
and injection_wait. You can then pass this combined function as an argument
to the proposed injection_points_attach() function.
Something as follows:
SELECT injection_points_attach('TestInjectionNoticeFunc',
'injection_points', 'injection_notice_and_wait');

PFA a rebased patch that contains the test.
The tests use the newly added SQL function to attach the injection_notice
function to an injection point
