Message:

Schema: Increase the length of wp_options.option_name.

It's pretty easy to run over the option_name length, which causes undefined behaviour when inserting and retrieving options. Increasing the length from VARCHAR(64) to VARCHAR(191) significantly reduces the risk of this occurring.

Because option_name has a UNIQUE index, we can only increase it to 191 characters, rather than 255. The index can only use a prefix of 191 characters, so will incorrectly restrict long different strings that have the same prefix, if we make the column longer.

Props scribu, OriginalEXE, khromov, MikeHansenMe, netweb, pento.

Fixes #13310.
