    Fix for bug #28464: a string argument to 'limit ?' PS - replication fails · 5b3b80b4

    Problem: we may get syntactically incorrect queries in the binary log 
    if we use a string value user variable executing a PS which 
    contains '... limit ?' clause, e.g.
    prepare s from "select 1 limit ?"; 
    set @A='qwe'; execute s using @A;
      
    Fix: raise an error in such cases.
