Not entirely sure about the rest of it, but if you want backend start
time, you can look at pg_stat_activity (which also happens to have the
pid).
If you want just your own, combine it with pg_backend_pid, as in:
select
pid || ',' || backend_start
from pg_stat_activity where pid = pg_backend_pid();
Thanks!
