    Description

      Add proper support for complex types containing collated strings in operations reverse, array_join, concat, map (create). Examples:

      select reverse('abc' collate utf8_binary_lcase);
      select reverse(array('a' collate utf8_binary_lcase, 'b' collate utf8_binary_lcase));
      select array_join(array('a' collate utf8_binary_lcase, 'b' collate utf8_binary_lcase), ', ' collate utf8_binary_lcase);
      select concat('a' collate utf8_binary_lcase, 'b' collate utf8_binary_lcase);
      select map('a' collate utf8_binary_lcase, 1, 'A' collate utf8_binary_lcase, 2);
