11100	delete_post_meta_by_key() is currently broken	Viper007Bond	westi	"`$wpdb->prepare()` quotes strings and therefore results in a broken query:

{{{
$wpdb->query( $wpdb->prepare(""DELETE FROM $wpdb->postmeta WHERE meta_id IN(%s)"", implode( ',', $postmetaids) ) );
}}}

It results in something like this:

{{{
DELETE FROM wp_postmeta WHERE meta_id IN('883,1062,1063,1064,1066,1067,969')
}}}

There are likely other places where this is also an issue."	defect (bug)	closed	normal	2.9	Database	2.9	normal	fixed	has-patch
