Wiki/News/Documents truncate contents to 64K in MYSQL

Description

I've found wiki posts over 64K get silently truncated. The problem is in the SQL specification of the following databases/fields is TEXT (64K) instead of MEDIUMTEXT (16MB) or LONGTEXT (>16MB):

table changesets comments
table comments comments
table documents description
table issues description
table journals notes
table messages content
table news description
table projects description
table wiki_contents text

Perhaps some of these don't need to change but I think most should be MEDIUMTEXT or LARGETEXT (documents for example)?

I have worked around this at my site with using the mysql command:

mysql> ALTER TABLE wiki_contents CHANGE text MEDIUMTEXT ;

but I'm afraid the next db migrate will mess it up, and others will hit it.

I suggest this is urgent priority, since data is lost.

There is also a BLOB in wiki_content_versions that should be MEDIUMBLOB or LARGEBLOB.

As described in #3777 this bug leads to silent loss of data for project users, is there any estimate on what release(s) the patch in #1404 or a similar solution will be included in?

Rewrite from the patch #1404 : set wiki content and versioned content up to 16MB.
I can eventually add a wiki content truncation detection system, but it'd cost a reload of the modified instance. Is this patch ok or should I add the check?

IMO 16MB is fine. It becomes a HTML page not an attachment, so 16MB is enough.

Will this go into 0.9?

I needed to split up some documents with big tables into two or more parts which isnt really nice.
