This is due to a flag column-statistics that is enabled by default in mysqldump 8. You can disable it by adding --column-statistics=0.
The command will be something like:
mysqldump --column-statistics=0 --host=<server> --user <user> --password <securepass>
To disable column statistics by default, you can add the following in a MySQL config file, such as /etc/my.cnf or ~/.my.cnf.
[mysqldump]
column-statistics=0
It’s brilliantly working for me.
More details about column-statistics:
Add ANALYZE TABLE statements to the output to generate histogram
statistics for dumped tables when the dump file is reloaded. This
option is disabled by default because histogram generation for large
tables can take a long time.
