Wikimedia Bugzilla is closed!

Should be fixed now, but I haven't tested it since I don't have PostgreSQL
installed.

PHP Warning:  pg_query(): Query failed: ERROR:  syntax error at or near "LIKE"
at character 39 in /var/www/html/gres/includes/DatabasePostgreSQL.php on line 99

With a couple more tweaks it's running now.

Broken again in r28547:

This is MediaWiki version 1.12alpha (r28547).

Reading tests from "maintenance/parserTests.txt"...

AFAIK, according to 'maintenance/postgres/compare_schemas.pl' : "searchindex          ## We use tsearch2 directly on the page table instead"

Fixed in r28627, thanks for the report.
