SELECT anon.dump() hanging

I've had success with in-place anonymization, but running this command produces no output at all, it just sits there forever (over 12 hours) burning CPU resources without generating a byte of output.

I'm not sure what details I can provide that would be most helpful? For example, I'm still trying to figure out whether there might be a problem with one of my masking rules (e.g. I had a problem with the fake email mask being used on a primary key field and of course generating duplicate keys). I can update this ticket with more info on my experiments here if this is relevant, but I was expecting, like pg_dump, to get some sort of output, and at worst an incomplete dump because of hitting these potentially flawed security labels.

This is with the current extension on PGXN, I've yet to compile and test against master but I will report back here if this would be desirable?

I apologize for such a vague report, but I figured some feedback would be helpful before deep diving here.
