Patch against r41664 that fixes the issue locally

When attempting to use Special:AllPages on a empty namespace on a local installation, I get a database error (quoted at the bottom of this report). The error doesn't occur on MySQL because the Database class for MySQL converts php's boolean false to the empty string rather than the integer 0, and anyway MySQL will allow odd comparisons like "string >= integer".

The attached patch (against r41664) seems to fix it for my local installation.

A database error has occurred
Query: SELECT page_title FROM page WHERE page_namespace = '1' AND (page_title >= 0) ORDER BY page_title ASC LIMIT 2 OFFSET 344
Function: SpecialAllpages::showToplevel
Error: 1 ERROR: operator does not exist: text >= integer
LINE 1: ... page WHERE page_namespace = '1' AND (page_title >= 0) ORD...
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
