Some are changes that partially implemented like
page_no_title_convert
field on page table that only appear in 32 hosts (around two third of the

mention of removing it neither its existence so I have no idea how to
proceed here.
Looks like it was added in r16524
<http://mediawiki.org/wiki/Special:Code/MediaWiki/16524> and reverted
(except for the release note entry) in r16526
<http://mediawiki.org/wiki/Special:Code/MediaWiki/16526>.
Or text table on 21 hosts (around half of them) has an
extra field called
inverse_timestamp which I can't find any mention of it in the code but
there used to be a field with this name in revision table that got dropped
in 2005 and I have no idea how to proceed here.
Revisions used to be stored much like how images still are: there was the
"cur" table that had data about the current revision, including its actual
content, and the "old" table for previous revisions.
When all this was redone to have "page" and "revision" and
"text" (r6710
<http://mediawiki.org/wiki/Special:Code/MediaWiki/6710>), the "old" table
was just renamed to "text" since most of the text was already in that
table. Which is why all the fields in text use "old_" as a prefix. It seems
that the extraneous columns weren't dropped on all wikis.
