It would be more clear what was happening if you used ps flags that
would include the parent process ID in the listing. My guess is that
process 1971 is a newly-forked backend that hasn't had a chance to
change its ps display yet. However, the window for that is pretty durn
short, so it's surprising that you'd see this on any regular basis.

If 1971 is not a child of 510 but of someone else, then you've got
trouble --- but finding out who the someone else is would be the first
step towards understanding the issue anyway.
