Re: shared-memory based stats collector - v70

Hi!

Found a place in the code of this patch that is unclear to me:

https://github.com/postgres/postgres/blob/1acf10549e64c6a52ced570d712fcba1a2f5d1ec/src/backend/utils/activity/pgstat.c#L1658

Owing assert() the next if() should never be performed, but the comment above says the opposite.
Is this assert really needed here? And if so, for what?

Would be glad for clarification.


With the best regards,
