> Add proper support for complex types containing collated strings in operations reverse, array_join, concat, map (create). Examples:
> {code:java}
> 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);{code}
