Bug in posts_tags table

If you read my previous article about strange bugs in posts_tag table, you must to know, I found "error", and now all work stable.

In Mysql table posts_tag, you must add column id (BIGINT, unique, autoincrease)
So, at least you had:

id BIGINT +
post_id
tag_id

And, if you editing any posts (clearing tag, for example) - other posts don't clear in this table.

Alliluja! ;-)
