I upgraded a mediawiki installation from 1.16-alpha to 1.17-alpha@72382.
After opening any Category page I get an error:

--------------------------------------------------------------------------
SELECT page_id,page_title,page_namespace,page_len,page_is_redirect,cl_sortkey,cat_id,cat_title,cat_subcats,cat_pages,cat_files,cl_sortkey_prefix FROM page INNER JOIN categorylinks ON ((cl_from = page_id)) LEFT JOIN category ON ((cat_title = page_title AND page_namespace = 14)) WHERE cl_to = 'category-name' AND cl_type = 'page' ORDER BY cl_sortkey LIMIT 201 ;

ERROR:  column "cl_sortkey_prefix" does not exist
LINE 1: ...,cat_id,cat_title,cat_subcats,cat_pages,cat_files,cl_sortkey...
                                                             ^
--------------------------------------------------------------------------
and the call site is in CategoryPage.php function doCategoryQuery().

I think that the cause is pretty simple: in commit 
72026 new columns were added:

+  cl_sortkey_prefix TEXT         NOT NULL  DEFAULT '',
+  cl_collation      SMALLINT     NOT NULL  DEFAULT 0,
+  cl_type           TEXT         NOT NULL  DEFAULT 'page'

I think that the fix is pretty simple:
add the missing columns when running maintenance/update.php:

ALTER TABLE categorylinks ADD COLUMN cl_sortkey_prefix TEXT NOT NULL DEFAULT '';
ALTER TABLE categorylinks ADD COLUMN cl_collation SMALLINT NOT NULL DEFAULT 0;
ALTER TABLE categorylinks ADD COLUMN cl_type TEXT NOT NULL DEFAULT 'page';

Seem to work after this change :)
