$databases = array_flip( $databases );
if ( !$databases ) {
$this->showError( 'config-no-db', $wgLang->commaList( $allNames )

// @todo FIXME: This only works for the web installer!
return false;
}
$this->setVar( '_CompiledDBs', $databases );
If we have already a cached list of dbs, but this count is still 0, attempt to
