When the worker is down for any reason the request queue will now reject insertions.
-- kill the worker
-- select pg_terminate_backend((select pid from pg_stat_activity where backend_type = 'pg_net worker'));
select net.http_get('https://github.com');
ERROR: the pg_net background worker must be up when doing requests
DETAIL: the pg_net background worker is down due to an internal error and cannot process requests
HINT: make sure that you didn't modify any of pg_net internal tables or used them for foreign key references
