hi @Aias00 , how about this similar pr #2329
@pwallk describe

the delNum argument cannot be passed correctly and should be changed instead：delete from hzb_history limit ?1,secondly postgresql does not support delete followed by limit，Therefore, it should be deleted with nested subqueries (earlier MySQL versions did not support nested subqueries, such as 5.7, 5.6, so two layers of nesting are used).
