Description Dieter 2007-11-15 19:11:30 UTC
We are using POSTGRES for our wiki.

When we like to see the differences of one page we receive a internal error like:

A database error has occurred Query: SELECT * FROM recentchanges WHERE rc_timestamp = '20071115153759' AND rc_this_oldid = '2698' AND rc_last_oldid = '2601' AND rc_patrolled = '0' Function: DifferenceEngine::showDiffPage Error: 1 FEHLER: ungültige Eingabesyntax für Typ timestamp with time zone: »20071115153759«

#7 /srv/www/htdocs/wiki/index.php(89): MediaWiki->initialize(Object(Title), Object(OutputPage), Object(User), Object(WebRequest))
#8 {main}

When I change the first parameter of wfTimestamp() in Revision:getTimestamp() from TS_MW to TS_POSTGRES everything works fine.

As I know, that changing Revision.php might make problems during the next update, I'd like to know what the correct solution would be.

Me again,

I had another problem with the combination of MediaWiki 1.11.0 und Postgres:

When we wanted to delete a unused image, we received internal errors as well:

A database error has occurred Query: INSERT INTO filearchive (fa_storage_group,fa_storage_key,fa_deleted_user,fa_deleted_timestamp,fa_deleted_reason,fa_deleted,fa_name,fa_archive_name,fa_size,fa_width,fa_height,fa_metadata,fa_bits,fa_media_type,fa_major_mime,fa_minor_mime,fa_description,fa_user,fa_user_text,fa_timestamp) SELECT 'deleted',IF(img_sha1='', '', CONCAT(img_sha1,'.png')),'2','2007-11-15 21:12:29 GMT','',0,img_name,NULL,img_size,img_width,img_height,img_metadata,img_bits,img_media_type,img_major_mime,img_minor_mime,img_description,img_user,img_user_text,img_timestamp FROM image WHERE img_name = 'Icon.produkt.png' Function: LocalFileDeleteBatch::doDBInserts Error: 1 FEHLER: Funktion concat(text, "unknown") existiert nicht HINT: Keine Funktion stimmt mit dem angegebenen Namen und den Argumenttypen überein. Sie müssen möglicherweise ausdrückliche Typumwandlungen hinzufügen.

#1 /srv/www/htdocs/wiki/includes/Database.php(1845): Database->query('INSERT INTO fi...', 'LocalFileDelete...')
#2 /srv/www/htdocs/wiki/includes/filerepo/LocalFile.php(1216): Database->insertSelect('filearchive', 'image', Array, Array, 'LocalFileDelete...')

#9 /srv/www/htdocs/wiki/index.php(89): MediaWiki->initialize(Object(Title), Object(OutputPage), Object(User), Object(WebRequest))
#10 {main}

With changing the LocalFile.php I could manage to overcome the problem:

 if ( $deleteCurrent ) {
                        $where = array( 'img_name' => $this->file->getName() );
                        $dbw->insertSelect( 'filearchive', 'image',
                                        'fa_storage_group' => $encGroup,
                                        'fa_storage_key'   => "CASE WHEN img_sha1 = '' THEN '' ELSE img_sha1 || $encExt END",

                                        'fa_deleted_user'      => $encUserId,
                                        'fa_deleted_timestamp' => $encTimestamp,
                                        'fa_deleted_reason'    => $encReason,
                                        'fa_deleted'               => 0,

                                        'fa_name'         => 'img_name',
                                        'fa_archive_name' => 'NULL',
                                        'fa_size'         => 0,
                                        'fa_width'        => 0,
                                        'fa_height'       => 0,
                                        'fa_metadata'     => 'img_metadata',
                                        'fa_bits'         => 0,
                                        'fa_media_type'   => 'img_media_type',
                                        'fa_major_mime'   => 'img_major_mime',
                                        'fa_minor_mime'   => 'img_minor_mime',
                                        'fa_description'  => 'img_description',
                                        'fa_user'         => 'img_user',
                                        'fa_user_text'    => 'img_user_text',
                                        'fa_timestamp'    => 'img_timestamp'
                                ), $where, __METHOD__ );

Both errors (version difference and file deletion) have already been solved under bug report nr 11331.
