Convert all tags to lowercase

[Bruno Bacha]

Hi,

I decided to convert all tags to lower case letters. Already activated the option to "Convert all tags to lowercase" but it seems that did not convert. I could run these commands below without compromising the database?

UPDATE core_tags SET tag_text = lower(tag_text);

UPDATE core_tags_cache SET tag_cache_text = lower(tag_cache_text);

Thanks.
