Comment (by archon810):

 I'm a bit confused. WP 4.2 changes the posts table and specifically the
 index on post_name to be 191 long, (which takes a long time on large
 tables, which is why I noticed). Reading over the reasoning, I was
 expecting the post_name field to be 400 long, but I still see it as 200 on
 all upgraded 4.2 instances.

 Should I be expecting the field name to change to 400 on existing tables
 or is this only for new ones created from 4.2 on?
