An UPDATE waits for FOR SHARE query to finish, and vice versa. In my
experiments I didn't see an UPDATE creating a multi-xact. Why do we
have UPDATEs in the load created by the test? Am I missing something?
As far as I remember, this was done on purpose to create different
multixact members statuses randomly.
In that case, better to include that in the comments.
I think that was indeed the purpose, but the test should use FOR KEY
SHARE rather than FOR SHARE. Otherwise the UPDATEs don't generate multixids.
